From: Krishna Gudipati <kgudipat@xxxxxxxxxxx>
Change details:
- The following patch adds back cleaned up (2.3.2.0) based BFA driver specific code:
bfad.c : Contains the BFA module load/unload, pci probe/remove,
interrupt handlers and user space firmware handling.
bfad_im.c : Contains the scsi_host_template definitions, entries
& IM specific code.
bfad_attr.c : Contains the fc_transport_template definitions and entries.
Signed-off-by: Krishna Gudipati <kgudipat@xxxxxxxxxxx>
