Obtaining a MAC address may be deferred in cases when the MAC is stored
in an NVMEM block, for example, and it may not be ready upon the first
retrieval attempt and return EPROBE_DEFER.
It is also possible that a port that does not rely on NVMEM has been
already created when getting the defer request. Thus, also the resources
allocated previously must be freed when doing a roll-back.

For RX TLS device-offloaded packets, the HW spec guarantees checksum
validation for the offloaded packets, but does not define whether the
CQE.checksum field matches the original packet (ciphertext) or
the decrypted one (plaintext). This latitude allows architetctural
improvements between generations of chips, resulting in different decisions
regarding the value type of CQE.checksum.
Hence, for these packets, the device driver should not make use of this CQE
field. Here we block CHECKSUM_COMPLETE usage for RX TLS device-offloaded
packets, and use CHECKSUM_UNNECESSARY instead.
Value of the packet's tcp_hdr.csum is not modified by the HW, and it always

2. When PHY is link up, it calls netif_carrier_on() and then

3. ftgmac100_adjust_link() will schedule the reset task
4. ftgmac100_reset_task() will then reset the MAC in another schedule
After step 2, systemd will be notified to send DHCP discover packet,

Increase this delay to 50 msec and use udelay() for the first 10 usec

Commit c503e63200 ("ice: Stop processing VF messages during teardown")
introduced a driver state flag, ICE_VF_DEINIT_IN_PROGRESS, which is
intended to prevent some issues with concurrently handling messages from
VFs while tearing down the VFs.
This change was motivated by crashes caused while tearing down and
bringing up VFs in rapid succession.
It turns out that the fix actually introduces issues with the VF driver
caused because the PF no longer responds to any messages sent by the VF
during its .remove routine. This results in the VF potentially removing
its DMA memory before the PF has shut down the device queues.
Additionally, the fix doesn't actually resolve concurrency issues within
the ice driver. It is possible for a VF to initiate a reset just prior
to the ice driver removing VFs. This can result in the remove task
concurrently operating while the VF is being reset. This results in
similar memory corruption and panics purportedly fixed by that commit.
Fix this concurrency at its root by protecting both the reset and
removal flows using the existing VF cfg_lock. This ensures that we
cannot remove the VF while any outstanding critical tasks such as a
virtchnl message or a reset are occurring.
This locking change also fixes the root cause originally fixed by commit
c503e63200 ("ice: Stop processing VF messages during teardown"), so we
can simply revert it.
Note that I kept these two changes together because simply reverting the
original commit alone would leave the driver vulnerable to worse race
conditions.

In switchdev mode, slow-path rules need to match all protocols, in order
to correctly redirect unfiltered or missed packets to the uplink. To set
this up for the virtual function to uplink flow, the rule that redirects
packets to the control VSI must have the tunnel type set to
ICE_SW_TUN_AND_NON_TUN. As a result of that new tunnel type being set,
ice_get_compat_fv_bitmap will select ICE_PROF_ALL. At that point all

ocelot_vlan_member_del() will free the struct ocelot_bridge_vlan, so if
this is the same as the port's pvid_vlan which we access afterwards,
what we're accessing is freed memory.
Fix the bug by determining whether to clear ocelot_port->pvid_vlan prior
to calling ocelot_vlan_member_del().

1588 Single Step Timestamping code path uses a mutex to
enforce atomicity for two events:
- update of ptp single step register
- transmit ptp event packet
Before this patch the mutex was not initialized. This
caused unexpected crashes in the Tx function.

Clang static analysis reports this representative problem
dpaa2-switch-flower.c:616:24: warning: The right operand of '=='

tmp->cfg.vlan_id == vlan) {

vlan is set in dpaa2_switch_flower_parse_mirror_key(). However
this function can return success without setting vlan. So
change the default return to -EOPNOTSUPP.

The COMMS package can enable the hardware parser to recognize IPSEC
frames with ESP header and SPI identifier. If this package is available
and configured for loading in /lib/firmware, then the driver will
succeed in enabling this protocol type for RSS.
This in turn allows the hardware to hash over the SPI and use it to pick
a consistent receive queue for the same secure flow. Without this all
traffic is steered to the same queue for multiple traffic threads from
the same IP address. For that reason this is marked as a fix, as the
driver supports the model, but it wasn't enabled.
If the package is not available, adding this type will fail, but the
failure is ignored on purpose as it has no negative affect.

If NIC had packets in tx queue at the moment link down event
happened, it could result in tx timeout when link got back up.
Since device has more than one tx queue we need to reset them
accordingly.
