100GbE Intel Wired LAN Driver Updates 2018-10-01
This series contains updates to ice driver only.
Anirudh provides several changes to "prep" the driver for upcoming
features. Specifically, the functions that are used for PF VSI/netdev
setup will also be used in SR-IOV support and to allow the reuse of
these functions, code needs to move.
Dave provides the only other change in the series, updates the driver to
protect the reset patch in its entirety. This is done by adding the
various bit checks to determine if a reset is scheduled/initiated and
whether it came from the software or firmware.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Currently, there is no bit, or set of bits, that protect the entirety
of the reset path.
If the reset is originated by the driver, then the relevant
one of the following bits will be set when the reset is scheduled:
__ICE_PFR_REQ
__ICE_CORER_REQ
__ICE_GLOBR_REQ
This bit will not be cleared until after the rebuild has completed.
If the reset is originated by the FW, then the first the driver knows of
it will be the reception of the OICR interrupt. The __ICE_RESET_OICR_RECV
bit will be set in the interrupt handler. This will also be the indicator
in a SW originated reset that we have completed the pre-OICR tasks and
have informed the FW that a reset was requested.
To utilize these bits, change the function:
ice_is_reset_recovery_pending()
to be:
ice_is_reset_in_progress()
The new function will check all of the above bits in the pf->state and
will return a true if one or more of these bits are set.

The functions that are used for PF VSI/netdev setup will also be used
for SR-IOV support. To allow reuse of these functions, move these
functions out of ice_main.c to ice_common.c/ice_lib.c
This move is done across multiple patches. Each patch moves a few
functions and may have minor adjustments. For example, a function that was
previously static in ice_main.c will be made non-static temporarily in
its new location to allow the driver to build cleanly. These adjustments
will be removed in subsequent patches where more code is moved out of
ice_main.c
In this particular patch, the following functions were moved out of
ice_main.c:
int ice_add_mac_to_list
ice_free_fltr_list
ice_stat_update40
ice_stat_update32
ice_update_eth_stats
ice_vsi_add_vlan

rx_mini_pending was set to an incorrect value. This was causing EINVAL to
always be returned to 'ethtool -G'. The driver does not support mini or
jumbo rings so the respective settings should be zero.
Also, change the valid range of the number of descriptors in the rings to
make the code simpler and easier for users to understand (this removes the
valid settings of 8 and 16). Add a system log message indicating when the
number is rounded-up from what the user specifies with the 'ethtool -G'
command (i.e. when it is not a multiple of 32), and update the log message
when a user-provided value is out of range to also indicate the stride.

We have MAX_FW_API_VER_BRANCH, MAX_FW_API_VER_MAJOR, and
MAX_FW_API_VER_MINOR that we use in ice_controlq.h to test when a
firmware version is newer than expected. This is currently tested by
comparing each field separately. Thus, we compare the branch field
against the MAX_FW_API_VER_BRANCH, and so forth.
This means that currently, if we suppose that the max firmware version
is defined as 0.2.1, i.e.
Then firmware 0.1.3 will fail to load. This is because the minor version
3 is greater than the max minor version 1.
This is not intuitive, because of the notion that increasing the major
firmware version to 2 should mean any firmware version with a major
version is less than 2 should be considered older than 2...
In order to allow both 0.2.1 and 0.1.3 to load, you would have to define
the "max" firmware version as 0.2.3.. It is possible that such
a firmware version doesn't even exist yet!
Fix this by replacing the current logic with an updated check that
behaves as follows:
First, we check the major version. If it is greater than the expected
version, then we prevent driver load. Additionally, a warning message is
logged to indicate to the system administrator that they need to update
their driver. This is now the only case where the driver will refuse to
load.
Second, if the major version is less than the expected version, we log
an information message indicating the NVM should be updated.
Third, if the major version is exact, we'll then check the minor
version. If the minor version is more than two versions less than
expected, we log an information message indicating the NVM should be
updated. If it is more than two versions greater than the expected
version, we log an information message that the driver should be
updated.
To support this, the ice_aq_ver_check function needs its signature
updated to pass the HW structure. Since we now pass this structure,
there is no need to pass the firmware API versions separately.

When shutting down the controlqs, we check if they are initialized
before we shut them down and destroy the lock. This is important, as it
prevents attempts to access the lock of an already shutdown queue.
Unfortunately, we checked rq.head and sq.head as the value to determine
if the queue was initialized. This doesn't work, because head is not
reset when the queue is shutdown. In some flows, the adminq will have
already been shut down prior to calling ice_shutdown_all_ctrlqs. This
can result in a crash due to attempting to access the already destroyed
mutex.
Fix this by using rq.count and sq.count instead. Indeed, ice_shutdown_sq
and ice_shutdown_rq already indicate that this is the value we should be
using to determine of the queue was initialized.

100GbE Intel Wired LAN Driver Updates 2018-09-27
This series contains fixes to the ice driver only.
Jake fixes a potential crash due to attempting to access the mutex which
is already destroyed. Fix this by using rq.count and sq.count to
determine if the queue was initialized. Fixed the current logic for
checking the firmware version to properly handle situations when
firmware major/minor versions differ and when the branch version
differs.
Bruce replaces a memcpy() with a direct assignment, which is preferred.
Also updated the branding strings and device ids supported by the
driver. Fixed the "ethtool -G" command in the driver, which was always
returning EINVAL when changing the descriptor ring size.
Brett update and clarified code comments.
Anirudh updates the driver to ensure we query the firmware for the
transmit scheduler node information before adding it to the driver
database, to ensure we have the current information. Also update the
"get capabilities" command to get device and function capabilities.

3 is greater than the max minor version 1.
This is not intuitive, because of the notion that increasing the major
firmware version to 2 should mean any firmware version with a major
version is less than 2 should be considered older than 2...
In order to allow both 0.2.1 and 0.1.3 to load, you would have to define
the "max" firmware version as 0.2.3.. It is possible that such
a firmware version doesn't even exist yet!
Fix this by replacing the current logic with an updated check that
behaves as follows:
First, we check the major version. If it is greater than the expected
version, then we prevent driver load. Additionally, a warning message is
logged to indicate to the system administrator that they need to update
their driver. This is now the only case where the driver will refuse to
load.
Second, if the major version is less than the expected version, we log
an information message indicating the NVM should be updated.
Third, if the major version is exact, we'll then check the minor
version. If the minor version is more than two versions less than
expected, we log an information message indicating the NVM should be
updated. If it is more than two versions greater than the expected
version, we log an information message that the driver should be
updated.
To support this, the ice_aq_ver_check function needs its signature
updated to pass the HW structure. Since we now pass this structure,
there is no need to pass the firmware API versions separately.

When shutting down the controlqs, we check if they are initialized
before we shut them down and destroy the lock. This is important, as it
prevents attempts to access the lock of an already shutdown queue.
Unfortunately, we checked rq.head and sq.head as the value to determine
if the queue was initialized. This doesn't work, because head is not
reset when the queue is shutdown. In some flows, the adminq will have
already been shut down prior to calling ice_shutdown_all_ctrlqs. This
can result in a crash due to attempting to access the already destroyed
mutex.
Fix this by using rq.count and sq.count instead. Indeed, ice_shutdown_sq
and ice_shutdown_rq already indicate that this is the value we should be
using to determine of the queue was initialized.

The mvneta controller can handle speeds up to 2500Mbps on the SGMII
interface. This relies on serdes configuration, the lane must be
configured at 3.125Gbps and we can't use in-band autoneg at that speed.
The main issue when supporting that speed on this particular controller
is that the link partner can send ethernet frames with a shortened
preamble, which if not explicitly enabled in the controller will cause
unexpected behaviours.
This was tested on Armada 385, with the comphy configuration done in
bootloader.

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.

Trival cleanup, list_move_tail will implement the same function that
list_del() + list_add_tail() will do. hence just replace them.
