Convert the memset/memcpy uses of 6 to ETH_ALEN
where appropriate.
Also convert some struct definitions and u8 array
declarations of [6] to ETH_ALEN.

If the administrator has not assigned a MAC address to the VF via the
PF then handle it gracefully by generating a temporary MAC address.
This ensures that we always know when we have a random address and
udev won't get upset about it.

Function name should include '_ether_addr'.
Return type should be bool.
Parameter name should be 'addr' not 'dest' (also matching kernel-doc).

In SR-IOV mode the PF driver acts as the uplink port and is
used to send control packets e.g. lldpad, stp, etc.
eth0.1 eth0.2 eth0
VF VF PF
| | | <-- stand-in for uplink
| | |
--------------------------
| Embedded Switch |
--------------------------
|
MAC <-- uplink
But the embedded switch is setup to forward multicast addresses
to all interfaces both VFs and PF and onto the physical link.
This results in reserved MAC addresses used by control protocols
to be forwarded over the switch onto the VF.
In the LLDP case the PF sends an LLDPDU and it is currently
being forwarded to all the VFs who then see the PF as a peer.
This is incorrect.
This patch adds the multicast addresses to the RAR table in the
hardware to prevent this behavior.

This change adds support for DCB and SR-IOV from the VF. With this change
in place the VF will correctly use a traffic class other than 0 in the case
that the PF is configured with the default user priority belonging to a
traffic class other than 0.

With recent kernel changes we can now return errors on a failure to setup a
VLAN filter. This patch takes advantage of that opportunity so that we can
return either an EIO error in the case of a mailbox failure, or an EACCESS
error in the case of being denied access to the VLAN filter table by the
PF.

The VF driver was not designed to correctly handle a message timeout. As
a result it is possible for one bad message to invalidate all messages
following it until the part is reset. Instead we should copy the example
in igbvf of how to handle a mailbox event and message timeout.

In ixgbevf_reset_hw_vf() msleep is called while holding mbx_lock

This change makes it so that the VF can support the PF/VF API negotiation
protocol. Specifically in this case we are adding support for API 1.0
which will mean that the VF is capable of cleaning up buffers that span
multiple descriptors without triggering an error.

This change moves the code for notifying the PF of the VF maximum packet
size into the vf.c file. The main motivation behind this is that the vf.c
file is supposed to contain all of the messages used when communicating
with the PF.
In addition it creates a separate function for setting the Rx buffer size
so that we have on centralized area to review what buffer sizes will be
requested by the VF.

Remove jump to out label that was skipping over code to replace the
ack bit in the mailbox cache variable. This was causing driver mailbox
routines that poll for the PF to ack a message to time out which would
in turn cause all other mailbox messages to fail. Also replace the
mailbox cache variable message indication bit when a message is found
so that other functions that choose to poll for a mailbox message from
the PF won't miss it.
