[PATCH 4.9 154/175] bnx2x: Fix enabling network interfaces without VFs

From: Greg Kroah-Hartman
Date: Mon Sep 20 2021 - 13:08:40 EST


From: Adrian Bunk <bunk@xxxxxxxxxx>

commit 52ce14c134a003fee03d8fc57442c05a55b53715 upstream.

This function is called to enable SR-IOV when available,
not enabling interfaces without VFs was a regression.
