92ed2eb7f4 net: phy: probe the PHY before determining the supported features
We will soon support asking the PHY at runtime to determine what
features it supports, rather than forcing it to be compile time.
But we should probe the PHY first. So probe the phy driver earlier.

PHY registers are only 16 bits wide, therefore, if the read was

3b5e74e0af net: phy: disregard "Clause 22 registers present" bit in get_phy_c45_devs_in_pkg
Bit 0 in register 1.5 doesn't represent a device but is a flag that
Clause 22 registers are present. Therefore disregard this bit when
populating the device list. If code needs this information it
should read register 1.5 directly instead of accessing the device
list.
Because this bit doesn't represent a device don't define a
MDIO_MMD_XYZ constant, just define a MDIO_DEVS_XYZ constant for
the flag in the device list bitmap.

v2:
- make masking of bit 0 more explicit
- improve commit message

a465047717 net: marvell: mvpp2: fix AN restart
phylink already limits which interface modes are able to call the
MACs AN restart function, but in any case, the commentry seems
incorrect: the AN restart bit does not automatically clear when
set.  This has been found via manual setting using devmem2, and
we can observe that the AN does indeed restart and complete, yet
the AN restart bit remains set.  Explicitly clear the AN restart
bit.

417f3d08fe net: marvell: mvpp2: read correct pause bits
When reading the pause bits in mac_link_state, mvpp2 was reporting
the state of the "active pause" bits, which are set when the MAC is
in pause mode.  This is not what phylink wants - we want the
negotiated pause state.  Fix the definition so we read the correct
bits.

d14e078f23 net: marvell: mvpp2: only reprogram what is necessary on mac_config
mac_config() can be called at any point, and the expected behaviour
from MAC drivers is to only reprogram when necessary - and certainly
avoid taking the link down on every call.

Unfortunately, mvpp2 does exactly that - it takes the link down, and
reprograms everything, and then releases the forced-link down.

This is bad, it can cause the link to bounce:

- SFP detects signal, disables LOS indication.
- SFP code calls into phylink, calling phylink_sfp_link_up() which
  triggers a resolve.
- phylink_resolve() calls phylink_get_mac_state() and finds the MAC
  reporting link up.
- phylink wants to configure the pause mode on the MAC, so calls
  phylink_mac_config()
- mvpp2 takes the link down temporarily, generating a MAC link down
  event followed by another MAC link event.
- phylink calls mac_link_up() and then processes the MAC link down
  event.
- phylink_resolve() gets called again, registers the link down, and
  calls mach_link_down() before re-running itself.
- phylink_resolve() starts again at step 3 above.  This sequence
  repeats.

GMAC versions prior to mvpp2 do not require the link to be taken down
except when certain link properties (eg, switching between SGMII and
1000base-X mode, or enabling/disabling in-band negotiation) are
changed.  Implement this for mvpp2.

316734fdcf net: marvell: mvpp2: fix stuck in-band SGMII negotiation
It appears that the mvpp22 can get stuck with SGMII negotiation.  The
symptoms are that in-band negotiation never completes and the partner
(eg, PHY) never reports SGMII link up, or if it supports negotiation
bypass, goes into negotiation bypass mode (which will happen when the
PHY sees that the MAC is alive but gets no response.)

Triggering the PHY end of the link to re-negotiate results in the
bypass bit clearing on the PHY, and then re-setting - indicating that
the problem is at the mvpp22 GMAC end.

Asserting the GMAC reset and de-asserting it resolves the issue.
Arrange to assert the GMAC reset at probe time, and deassert it only
after we have configured the GMAC for the appropriate mode.  This
resolves the issue.

388ca27ffd net: marvell: mvpp2: phylink compliance updates
Sven Auhagen reported issues with negotiation on a couple of his
platforms using a mixture of SFP and PHYs in various different
modes.  Debugging to root cause proved difficult, but essentially
the problem comes down to the mvpp2 phylink implementation being
slightly at odds with what is expected.

phylink operates in three modes: phy, fixed-link, and in-band mode.

In the first two modes, the expected behaviour from a MAC driver is
that phylink resolves the operating mode and passes the mode to the
MAC driver for it to program, including when the link should be
brought up or taken down.  This is basically the same as the libphy
approach.  This does not negate the requirement to advertise a correct
control word for interface modes that have control words where that
can be reasonably controlled.

The second mode is in-band mode, where the MAC is expected to use the
in-band control word to determine the operating mode.

The mvneta driver implements the correct pattern required to support
this: configure the port interface type separately from the in-band
mode(s).  This is now specified in the phylink documentation patches.

mvpp2 was programming in-band mode for SGMII and the 802.3z modes no
what, and avoided forcing the link up in fixed/phy modes.  This caused
a problem with some boards where the PHY is by default programmed to
enter AN bypass mode, the PHY would report that the link was up, but
the mvpp2 never completed the exchange of control word.

Another issue that mvpp2 has is it sets SGMII AN format control word
for both SGMII and 802.3z modes. The format of the control word is
defined by MVPP2_GMAC_INBAND_AN_MASK, which should be set for SGMII
and clear for 802.3z. Available Marvell documentation for earlier
GMAC implementations does not make this clear, but this has been
ascertained via extensive testing on earlier GMAC implementations,
and then confirmed with a Macchiatobin Single Shot connected to a
Clearfog: when MVPP2_GMAC_INBAND_AN_MASK is set, the clearfog does
not receive the advertised pause mode settings.

Lastly, there is no flow control in the in-band control word in Cisco
SGMII, setting the flow control autonegotiation bit even with a PHY
that has the Marvell extension to send this information does not result
in the flow control being enabled at the MAC.  We need to do this
manually using the information provided via phylink.

Re-code mvpp2's mac_config() and mac_link_up() to follow this pattern.
This allows Sven Auhagen's board and Macchiatobin to reliably bring
the link up with the 88e1512 PHY with phylink operating in PHY mode
with COMPHY built as a module but the rest of the networking built-in,
and u-boot having brought up the interface.  in-band mode requires an
additional patch to resolve another problem.

439bb9edd4 ixgbe: Use struct_size() helper
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

Notice that, in this case, variable size is not necessary, hence
it is removed.

93c0970493 net: phy: consider latched link-down status in polling mode
The link status value latches link-down events. To get the current
status we read the register twice in genphy_update_link(). There's
a potential risk that we miss a link-down event in polling mode.
This may cause issues if the user e.g. connects his machine to a
different network.

On the other hand reading the latched value may cause issues in
interrupt mode. Following scenario:

- After boot link goes up
- phy_start() is called triggering an aneg restart, hence link goes
  down and link-down info is latched.
- After aneg has finished link goes up and triggers an interrupt.
  Interrupt handler reads link status, means it reads the latched
  "link is down" info. But there won't be another interrupt as long
  as link stays up, therefore phylib will never recognize that link
  is up.

Deal with both scenarios by reading the register twice in interrupt
mode only.

e5e7962ee5 mlxsw: spectrum_acl: Implement region migration according to hints
If the hints are returned, the migration should be started. For that to
happen, there is a need to create a second physical region in TCAM with
new ERP set by passing the hints and then move chunk by chunk,
entry by entry.

During the transition, two lookups will occur. One in old region and
another in new region. The highest priority rule will be chosen.

In an unlikely case that the migration will fail and also rollback to
original region will fail the vregion will become in bad state.
Everything will work, only no future rehash will be possible. In a
follow-up work, this can be resolved by trying to resume the rollback
in delayed work and repair the vregion.

c4c2dc5429 mlxsw: spectrum_acl: Split entry struct into entry and ventry
Do the split of entry struct so the new entry struct is related to the
actual HW entry, whereas ventry struct is a SW abstration of that.
This split prepares possibility for ventry to hold 2 HW entries which
is needed for region ERP rehash flow.

9069a3817d lib: objagg: implement optimization hints assembly and use hints for object creation
Implement simple greedy algo to find more optimized root-delta tree for
a given objagg instance. This "hints" can be used by a driver to:
1) check if the hints are better (driver's choice) than the original
   objagg tree. Driver does comparison of objagg stats and hints stats.
2) use the hints to create a new objagg instance which will construct
   the root-delta tree according to the passed hints. Currently, only a
   simple greedy algorithm is implemented. Basically it finds the roots
   according to the maximal possible user count including deltas.

7c62cfb8c5 devlink: publish params only after driver init is done
Currently, user can do dump or get of param values right after the
devlink params are registered. However the driver may not be initialized
which is an issue. The same problem happens during notification
upon param registration. Allow driver to publish devlink params
whenever it is ready to handle get() ops. Note that this cannot
be resolved by init reordering, as the "driverinit" params have
to be available before the driver is initialized (it needs the param
values there).

c675e06a98 ipvlan: decouple l3s mode dependencies from other modes
Right now ipvlan has a hard dependency on CONFIG_NETFILTER and
otherwise it cannot be built. However, the only ipvlan operation
mode that actually depends on netfilter is l3s, everything else
is independent of it. Break this hard dependency such that users
are able to use ipvlan l3 mode on systems where netfilter is not
compiled in.

Therefore, this adds a hidden CONFIG_IPVLAN_L3S bool which is
defaulting to y when CONFIG_NETFILTER is set in order to retain
existing behavior for l3s. All l3s related code is refactored
into ipvlan_l3s.c that is compiled in when enabled.
