qlcnic: VF-PF communication channel implementation
o Adapter provides communication channel between VF and PF.
Any control commands from the VF driver are sent to the PF driver
through this communication channel. PF driver validates the
commands before sending them to the adapter. Similarly PF driver
forwards any control command responses to the VF driver
through this communication channel. Adapter sends message pending
event to VF or PF when there is an outstanding response or a command
for VF or PF respectively. When a command or a response is sent over
a channel VF or PF cannot send another command or a response
until adapter sends a channel free event. Adapter allocates 1K area to
VF and PF each for this communication.
o Commands and responses are encapsulated in a header. Header determines
sequence id, number of fragments, fragment number etc.
