We don't get any further EVENT from an esd CAN USB device for changes
on REC or TEC while those counters converge to 0 (with ecc == 0). So
when handling the "Back to Error Active"-event force txerr = rxerr =
0, otherwise the berr-counters might stay on values like 95 forever.

Also, to make life easier during the ongoing development a
netdev_dbg() has been introduced to allow dumping error events send by
an esd CAN USB device.

nvme initialize core quirks before calling nvme_init_subsystem

BugLink: https://bugs.launchpad.net/bugs/2003596

[ Upstream commit 6f2d71524bcfdeb1fcbd22a4a92a5b7b161ab224 ]

A device might have a core quirk for NVME_QUIRK_IGNORE_DEV_SUBNQN
(such as Samsung X5) but it would still give a:

"missing or invalid SUBNQN field"

warning as core quirks are filled after calling nvme_init_subnqn. Fill
ctrl->quirks from struct core_quirks before calling nvme_init_subsystem
to fix this.

Tested on a Samsung X5.

i40e: Disallow ip4 and ip6 l4_4_bytes

BugLink: https://bugs.launchpad.net/bugs/2003596

[ Upstream commit d64aaf3f7869f915fd120763d75f11d6b116424d ]

Return -EOPNOTSUPP, when user requests l4_4_bytes for raw IP4 or
IP6 flow director filters. Flow director does not support filtering
on l4 bytes for PCTYPEs used by IP4 and IP6 filters.
Without this patch, user could create filters with l4_4_bytes fields,
which did not do any filtering on L4, but only on L3 fields.

i40e: Fix for VF MAC address 0

BugLink: https://bugs.launchpad.net/bugs/2003596

[ Upstream commit 08501970472077ed5de346ad89943a37d1692e9b ]

After spawning max VFs on a PF, some VFs were not getting resources and
their MAC addresses were 0. This was caused by PF sleeping before flushing
HW registers which caused VIRTCHNL_VFR_VFACTIVE to not be set in time for
VF.

Fix by adding a sleep after hw flush.

i40e: Fix not setting default xps_cpus after reset

BugLink: https://bugs.launchpad.net/bugs/2003596

[ Upstream commit 82e0572b23029b380464fa9fdc125db9c1506d0a ]

During tx rings configuration default XPS queue config is set and
__I40E_TX_XPS_INIT_DONE is locked. __I40E_TX_XPS_INIT_DONE state is
cleared and set again with default mapping only during queues build,
it means after first setup or reset with queues rebuild. (i.e.
ethtool -L <interface> combined <number>) After other resets (i.e.
ethtool -t <interface>) XPS_INIT_DONE is not cleared and those default
maps cannot be set again. It results in cleared xps_cpus mapping
until queues are not rebuild or mapping is not set by user.

Add clearing __I40E_TX_XPS_INIT_DONE state during reset to let
the driver set xps_cpus to defaults again after it was cleared.

net: mvneta: Fix an out of bounds check

BugLink: https://bugs.launchpad.net/bugs/2003596

[ Upstream commit cdd97383e19d4afe29adc3376025a15ae3bab3a3 ]

In an earlier commit, I added a bounds check to prevent an out of bounds
read and a WARN(). On further discussion and consideration that check
was probably too aggressive. Instead of returning -EINVAL, a better fix
would be to just prevent the out of bounds read but continue the process.

Background: The value of "pp->rxq_def" is a number between 0-7 by default,
or even higher depending on the value of "rxq_number", which is a module
parameter. If the value is more than the number of available CPUs then
it will trigger the WARN() in cpu_max_bits_warn().

[ Upstream commit 803e84867de59a1e5d126666d25eb4860cfd2ebe ]

Blamed commit claimed rcu_read_lock() was held by ip6_fragment() callers.

It seems to not be always true, at least for UDP stack.

net: plip: don't call kfree_skb/dev_kfree_skb() under spin_lock_irq()

BugLink: https://bugs.launchpad.net/bugs/2003596

[ Upstream commit 7d8c19bfc8ff3f78e5337107ca9246327fcb6b45 ]

It is not allowed to call kfree_skb() or consume_skb() from
hardware interrupt context or with interrupts being disabled.
So replace kfree_skb/dev_kfree_skb() with dev_kfree_skb_irq()
and dev_consume_skb_irq() under spin_lock_irq().
