Update the netdev permanent address during fm10k_reinit enables the user
to immediately see the new MAC address on the VF even if the device
isn't up. The previous code required that the device by opened before
changes would appear.

This allows us to correctly add a VLAN even if it matches our default
VID. However, we don't want to remove the VID rules once that VLAN is
deleted. Correctly remove the stack layers information of the VLAN, but
then return to forwarding that VID as untagged frames. If we deleted the
VID rules here, we would begin dropping traffic due to VLAN membership
violations.

l2_accel was checked for NULL at the top of fm10k_dfwd_del_station, and
we return if it is not defined. Due to this, we already know it can't be
null here so a separate check is meaningless. Discovered via cppcheck.

This change fixes an issue with adding an invalid multicast address
using the iproute2 tool (ip maddr add <MADDR> dev <dev>). The iproute2
tool and the kernel do not validate or filter the multicast addresses
when adding them to the multicast list. Thus, when synchronizing this
list with an invalid entry, the action will be aborted with an error
since the fm10k driver currently validates the list. Consequently,
multicast entries beyond the invalid one will not be processed and
communicated with the switch via the mailbox. This change makes it so
that invalid addresses will simply be skipped and allows synchronizing
the full list to proceed.

When the PF receives a request to update a multicast address for the VF,
it checks the enabled multicast mode first. Fix a bug where the VF tried
to set a multicast address before requesting the required xcast mode.
This ensures the multicast addresses are honored as long as the xcast
mode was allowed.

This change adds support for the Linux PTP Hardware clock and timestamping
functionality provided by the hardware. There are actually two cases that
this timestamping is meant to support.
The first case would be an ordinary clock scenario. In this configuration
the host interface does not have access to BAR 4. However all of the host
interfaces should be locked into the same boundary clock region and as such
they are all on the same clock anyway. With this being the case they can
synchronize among themselves and only need to adjust the offset since they
are all on the same clock with the same frequency.
The second case is a boundary clock scenario. This is a special case and
would require both BAR 4 access, and a means of presenting a netdev per
boundary region. The current plan is to use DSA at some point in the
future to provide these interfaces, but the DSA portion is still under
development.

This patch adds support for L2 MACVLAN by making use of the fact that the
RRC provides a unique tag per filter called a Global Resource Tag, or GLORT.
In the case of this offload what I have done is assigned a linear block of
these so that each GLORT represents one of the MACVLAN netdevs. By doing
this I can share the Rx queues and Tx queues for all of the MACVLAN netdevs
while allowing them to be demuxed in the Rx cleanup path.
