Subject: [PATCH 5.7 400/477] bnxt_en: Re-enable SRIOV during resume.

From: Michael Chan <michael.chan@...adcom.com>

[ Upstream commit 59ae210173ff86256fa0cdba4ea4d608c61e123d ]

If VFs are enabled, we need to re-configure them during resume because
firmware has been reset while resuming.  Otherwise, the VFs won't
work after resume.

Fixes: c16d4ee0e397 ("bnxt_en: Refactor logic to re-enable SRIOV after firmware reset detected.")
