This patch adds support for the PF <-> VF mailbox. It functions similar to
the PF <-> SM mailbox however there are several modifications made to
improve the reliability of the mailbox itself. In addition the PF/VF
mailbox is much smaller an only supports a total size of 16 DWORDs vs the
1024 DWORDS provided for the PF/SM mailbox.

This patch adds support for the mailbox that connects the PF to the Switch
Management entity. This mailbox will pass TLV formatted messages between
the two entities by using a pair of shared ring buffers.
The primary use of the mailbox is to configure L2 forwarding addresses,
VLANs, and general resource allocation from the switch.

This patch adds generic mailbox support. The general idea of the mailboxes
is to use a pair of ring buffers, one for request, one for response to send
data between the local driver and some remote entity be it the PF of the
Switch Manager.
