Hello Greg,
Although this patch fixes the actual issue but the patch is dependent on below patch as those were part of same series, due to this it fails to apply probably.
commit b7a49f73059fe6147b6b78e8f674ce0d21237432
Author: Manish Chopra <manishc@xxxxxxxxxxx>

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.
