Subject[PATCH 5.5 020/367] bnxt_en: Refactor logic to re-enable SRIOV after firmware reset detected.
Date
From: Michael Chan <michael.chan@broadcom.com>

[ Upstream commit c16d4ee0e397163fe7ceac281eaa952e63fadec7 ]

Put the current logic in bnxt_open() to re-enable SRIOV after detecting
firmware reset into a new function bnxt_reenable_sriov(). This call
needs to be invoked in the firmware reset path also in the next patch.
