commit 802d4d207e75d7208ff75adb712b556c1e91cf1c upstream
Commit 0a6890b9b4df ("bnx2x: Utilize FW 7.13.15.0.") added validation for fastpath HSI versions for different client init which was not meant for SR-IOV VF clients, which resulted in firmware asserts when running VF clients with different fastpath HSI version.
This patch along with the new firmware support in patch #1 fixes this behavior in order to not validate fastpath HSI version for the VFs.
