Subject: [PATCH v2 net-next 1/2] bnx2x: Utilize firmware 7.13.21.0
This new firmware addresses few important issues and enhancements
as mentioned below -
- Support direct invalidation of FP HSI Ver per function ID, required for
invalidating FP HSI Ver prior to each VF start, as there is no VF start
- BRB hardware block parity error detection support for the driver
- Fix the FCOE underrun flow
- Fix PSOD during FCoE BFS over the NIC ports after preboot driver
- Maintains backward compatibility
This patch incorporates this new firmware 7.13.21.0 in bnx2x driver.

v1->v2:
------------
* Modified the patch such that driver to be backward compatible
with older firmware too (New fw v7.13.21.0 on linux-firmware.git
enables driver to maintain backward compatibility)
