Subject: [PATCH net net 5/9] bnx2x: Fix config when SR-IOV and iSCSI are
 enabled

From: Ariel Elior <ariele@...adcom.com>

Starting with commit b9871bc "bnx2x: VF RSS support - PF side", if a PF will
have SR-IOV supported in its PCI configuration space, storage drivers will not
work for that interface.

This patch fixes the resource calculation to allow such a configuration to
properly work.
