Subject: [PATCH 1/5] bfa: Brocade BFA FC SCSI driver (bfad)

From: Krishna Chaitanya Gudipati <kgudipat@...cade.com>

This patch contains Brocade linux driver specific code that interfaces to 
upper layer linux kernel for PCI, SCSI mid-layer, sysfs related stuff. The 
code handles things such as module load/unload, PCI probe/release, handling
interrupts, interfacing with sysfs etc. It interacts with the firmware/hardware
via the code under files with prefix bfa_*.
