During systemd reboot sequence network driver interface is shutdown
by e1000_close. The PCI driver interface is shut by e1000_shutdown.
The e1000_shutdown checks for netif_running status, if still up it
brings down driver. But it disables msi outside of this if statement,
regardless of netif status. All this is OK when e1000_close happens
after shutdown. However, by default, everything in systemd is done
in parallel. This creates a conditions where e1000_shutdown is called
after e1000_close, therefore hitting BUG_ON assert in free_msi_irqs.

xemaclite_remove_ndev() is a simple wrapper around free_netdev()

Lookup in the ATU can be performed starting from a given MAC
address. This is faster than starting with the first possible MAC
address and iterating all entries.
Entries are returned in numeric order. So if the MAC address returned
is bigger than what we are searching for, we know it is not in the
ATU.

Inserting the TSB means adding an extra 8 bytes in front the of packet
that is going to be used as metadata information by the TDMA engine, but
stripped off, so it does not really help with the packet padding.
For some odd packet sizes that fall below the 60 bytes payload (e.g: ARP)
we can end-up padding them after the TSB insertion, thus making them 64
bytes, but with the TDMA stripping off the first 8 bytes, they could
still be smaller than 64 bytes which is required to ingress the switch.
Fix this by swapping the padding and TSB insertion, guaranteeing that
the packets have the right sizes.

There are two problems with EEPROM access. One is that it needs to
hold the semaphore until the entire response is read or else the
response can be corrupted by other firmware accesses. The second
problem is that acquiring and releasing the semaphore is slow, so
it should be taken and released once when multiple EEPROM accesses
will be done.
Both of these issues can be solved by adding a new function,
ixgbe_hic_unlocked, to issue firmware commands that will assume
that the caller has acquired the needed semaphore.

There are two methods for setting mac addresses in a Macvlan, that
differentiate themselves in the function macvlan_set_mac_Address.
If the macvlan mode is passthru, then we use the dev_set_mac_address
method, otherwise we use the dev_uc api via macvlan_sync_addresses.
The latter method (which would stem from using any non-passthru mode,
like bridge, or vepa), calls down into the driver in a path that terminates
in ixgbevf_set_uc_addr_vf, which sends a IXGBE_VF_SET_MACVLAN message,
which causes the pf to spawn the noted error message. This occurs because
it appears that the guest is trying to delete the mac address of the macvlan
before adding another.
The other path in macvlan_set_mac_address uses dev_set_mac_address, which
calls into ixgbevf_set_mac which uses the IXGBE_VF_SET_MAC_ADDR to the
pf to set the macvlan mac address.
The discrepancy here is in the handlers. The handler function for
IXGBE_VF_SET_MAC_ADDR (ixgbe_set_vf_mac_addr) has a check for
the vfinfo[].trusted bit to allow the operation if the vf is trusted.
In comparison, the IXGBE_VF_SET_MACVLAN message handler
(ixgbe_set_vf_macvlan_msg) has no such check of the trusted bit.

Some x550 devices require the driver version reported to its firmware; this
patch sends the driver version string to the firmware through the host
interface command for x550 devices.

FEC is configured by the NVM and the driver should not be
overriding it.

When VXLAN offloading is enabled, be_features_check() tries to check if
an encapsulated packet is indeed a VXLAN packet. The check is not strict
enough, and considers any UDP-encapsulated ethernet frame with a 8-byte
tunnel header as being VXLAN. Unfortunately, both GENEVE and VXLAN-GPE
have a 8-byte header, so they get through this check.
Force the UDP destination port to be the one that has been offloaded to
hardware.
Without this, GENEVE-encapsulated packets can end up having an incorrect
checksum when both a GENEVE and a VXLAN (offloaded) tunnel are
configured.
This is similar to commit a547224dceed ("mlx4e: Do not attempt to
offload VXLAN ports that are unrecognized").
