bnx2x: Support probing and removing of VF device
To support probing and removing of a bnx2x virtual function the following were added: 1. add bnx2x_vfpf.h: defines the VF to PF channel 2. add bnx2x_sriov.h: header for bnx2x SR-IOV functionality 3. enumerate VF hw types (identify VFs) 4. if driving a VF, map VF bar 5. if driving a VF, allocate Vf to PF channel 6. refactor interrupt flows to include VF Signed-off-by: Ariel Elior <ariele@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.
