This patch adds support for the mailbox that connects the PF to the Switch

Some firmware revisions don't wait for beacon tx
completion before sending another SWBA event. This
could lead to hardware using old (freed) beacon
data in some cases, e.g. tx credit starvation
combined with missed TBTT. This is very very rare.
On non-IOMMU-enabled hosts this could be a
possible security issue because hw could beacon
some random data on the air. On IOMMU-enabled
hosts DMAR faults would occur in most cases and
target device would crash.
Since there are no beacon tx completions (implicit
nor explicit) propagated to host the only
workaround for this is to allocate a DMA-coherent
buffer for a lifetime of a vif and use it for all
beacon tx commands. Worst case for this approach
is some beacons may become corrupted, e.g. garbled
IEs or out-of-date TIM bitmap.
Keep the original beacon-related code as-is in
case future firmware revisions solve this problem
so that the old path can be easily re-enabled with
a fw_feature flag.

We should not be manipulaging the DMA_CTRL registers directly by writing
0 to them to disable DMA. This is an operation that needs to be timed to
make sure the DMA engines have been properly stopped since their state
machine stops on a packet boundary, not immediately.
Make sure that tha bcmgenet_fini_dma() calls bcmgenet_dma_teardown() to
ensure a proper DMA engine state. As a result, we need to reorder the
function bodies to resolve the use dependency.

The GENET driver supports SKB fragments, and succeeds in transmitting
them properly, but when reclaiming these transmitted fragments, we will
only update the count of free buffer descriptors by 1, even for SKBs
with fragments. This leads to the networking stack thinking it has more
room than the hardware has when pushing new SKBs, and backing off
consequently because we return NETDEV_TX_BUSY.
Fix this by accounting for the SKB nr_frags plus one (itself) and update
ring->free_bds accordingly with that value for each iteration loop in
__bcmgenet_tx_reclaim().

Since commit 412ca1550c ("macvlan: Move broadcasts into a work queue"), the
driver uses tx_queue_len of the master device as the limit of packets enqueuing.
Problem is that virtual drivers have this value set to 0, thus all broadcast
packets were rejected.
Because tx_queue_len was arbitrarily chosen, I replace it with a static limit
of 1000 (also arbitrarily chosen).

There is a chance that the VF mlx4 RoCE driver (mlx4_ib) may see a 0-mac
as the current default MAC address when a RoCE interface first comes up.
In this case, the RoCE driver registers the 0-mac to get its MAC index --
used in the INIT2RTR transition when it creates its proxy Q1 qp's.
If we do not allow QP1 to be created, the RoCE driver will not come up.
If we do not register the 0-mac, but simply use a random mac-index,
QP1 will attempt to send packets with an someone's else source MAC which
will get the system into more troubled.
Since a 0-mac was previously used to indicate a free slot, this leads to
errors, both when the 0-mac is registered and when it is unregistered.
The required fix is to check in addition that the slot containing the
0-mac has a reference count of zero.
Additionally, when comparing MAC addresses, need to mask out the 2 MSBs
of the u64 mac on both sides of the comparison.
Note that when the EN driver (mlx4_en) comes up, it set itself a proper
mac --> the RoCE driver gets to be notified on that and further handing
is done with the update qp command, as was added by commit 9433c18891
("IB/mlx4: Invoke UPDATE_QP for proxy QP1 on MAC changes").
