This patch adds a new ingress hook for the inet family. The inet ingress
hook emulates the IP receive path code, therefore, unclean packets are
drop before walking over the ruleset in this basechain.
This patch also introduces the nft_base_chain_netdev() helper function
to check if this hook is bound to one or more devices (through the hook
list infrastructure). This check allows to perform the same handling for
the inet ingress as it would be a netdev ingress chain from the control
plane.

This patch adds the NF_INET_INGRESS pseudohook for the NFPROTO_INET
family. This is a mapping this new hook to the existing NFPROTO_NETDEV
and NF_NETDEV_INGRESS hook. The hook does not guarantee that packets are
inet only, users must filter out non-ip traffic explicitly.
This infrastructure makes it easier to support this new hook in nf_tables.

Offload tc-vlan mangle to mscc_ocelot switch
This series offloads one more action to the VCAP IS1 ingress TCAM, which

Create a test that changes a VLAN ID from 200 to 300.
We also need to modify the preferences of the filters installed for the

When the Extraction Frame Header contains a valid classified VLAN, use
that instead of the VLAN header present in the packet.

The VCAP_IS1_ACT_VID_REPLACE_ENA action, from the VCAP IS1 ingress TCAM,
changes the classified VLAN.
We are only exposing this ability for switch ports that are under VLAN
aware bridges. This is because in standalone ports mode and under a
bridge with vlan_filtering=0, the ocelot driver configures the switch to
operate as VLAN-unaware, so the classified VLAN is not derived from the
802.1Q header from the packet, but instead is always equal to the
port-based VLAN ID of the ingress port. We _can_ still change the
classified VLAN for packets when operating in this mode, but the end
result will most likely be a drop, since both the ingress and the egress
port need to be members of the modified VLAN. And even if we install the
new classified VLAN into the VLAN table of the switch, the result would
still not be as expected: we wouldn't see, on the output port, the
modified VLAN tag, but the original one, even though the classified VLAN
was indeed modified. This is because of how the hardware works: on
egress, what is pushed to the frame is a "port tag", which gives us the
following options:
- Tag all frames with port tag (derived from the classified VLAN)
- Tag all frames with port tag, except if the classified VLAN is 0 or
equal to the native VLAN of the egress port
- No port tag
Needless to say, in VLAN-unaware mode we are disabling the port tag.
Otherwise, the existing VLAN tag would be ignored, and a second VLAN
tag (the port tag), holding the classified VLAN, would be pushed
(instead of replacing the existing 802.1Q tag). This is definitely not
what the user wanted when installing a "vlan modify" action.
So it is simply not worth bothering with VLAN modify rules under other
configurations except when the ports are fully VLAN-aware.

This is a methodical transition of the driver from phylib
to phylink, following the guidelines from sfp-phylink.rst.
The MAC register configurations based on interface mode
were moved from the probing path to the mac_config() hook.
MAC enable and disable commands (enabling Rx and Tx paths
at MAC level) were also extracted and assigned to their
corresponding phylink hooks.
As part of the migration to phylink, the serdes configuration
from the driver was offloaded to the PCS_LYNX module,
introduced in commit 0da4c3d393 ("net: phy: add Lynx PCS module"),
the PCS_LYNX module being a mandatory component required to

Move the skb_headroom check out of fr_hard_header and into pvc_xmit.
This has two benefits:
1. Originally we only do this check for skbs sent by users on Ethernet-
emulating PVC devices. After the change we do this check for skbs sent on
normal PVC devices, too.
(Also add a comment to make it clear that this is only a protection
against upper layers that don't take dev->needed_headroom into account.
Such upper layers should be rare and I believe they should be fixed.)
2. After the change we can simplify the parameter list of fr_hard_header.
We no longer need to use a pointer to pointers (skb_p) because we no
longer need to replace the skb inside fr_hard_header.

netlink: export policy on validation failures
Export the policy used for attribute validation when it fails,
so e.g. for an out-of-range attribute userspace immediately gets
the valid ranges back.
v2 incorporates the suggestion from Jakub to have a function to
estimate the size (netlink_policy_dump_attr_size_estimate()) and
check that it does the right thing on the *normal* policy dumps,
not (just) when calling it from the error scenario.
v3 only addresses a few minor style issues.
v4 fixes up a forgotten 'git add' ... sorry.
v5 is a resend, I messed up v4's cover letter subject (saying v3)
and apparently the second patch didn't go out at all.
Tested using nl80211/iw in a few scenarios, seems to work fine
and return the policy back, e.g.
kernel reports: integer out of range
policy: 04 00 0b 00 0c 00 04 00 01 00 00 00 00 00 00 00
^ padding
^ minimum allowed value
policy: 04 00 0b 00 0c 00 05 00 ff ff ff ff 00 00 00 00
^ padding
^ maximum allowed value
policy: 08 00 01 00 04 00 00 00
