qlcnic: VF-PF communication channel implementation o Adapter provides communication channel between VF and PF.

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.

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. Signed-off-by: Manish Chopra <manish.chopra@qlogic.com> Signed-off-by: Sucheta Chakraborty <sucheta.chakraborty@qlogic.com> Signed-off-by: Rajesh Borundia <rajesh.borundia@qlogic.com> Signed-off-by: David S.
