Subject: bnxt_en: Refactor logic to re-enable SRIOV after firmware reset detected.
X-Git-Tag: v5.6-rc1~61^2~8^2~3
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=c16d4ee0e397163fe7ceac281eaa952e63fadec7;p=users%2Fjedix%2Flinux-maple.git

bnxt_en: Refactor logic to re-enable SRIOV after firmware reset detected.

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.
