From: Petr Oros Date: Fri, 11 Aug 2023 08:07:01 +0000 (+0200) Subject: Revert "ice: Fix ice VF reset during iavf initialization" X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0ecff05e6c59dd82dbcb9706db911f7fd9f40fb8;p=linux.git Revert "ice: Fix ice VF reset during iavf initialization" This reverts commit 7255355a0636b4eff08d5e8139c77d98f151c4fc. After this commit we are not able to attach VF to VM: virsh attach-interface v0 hostdev --managed 0000:41:01.0 --mac 52:52:52:52:52:52 error: Failed to attach interface error: Cannot set interface MAC to 52:52:52:52:52:52 for ifname enp65s0f0np0 vf 0: Resource temporarily unavailable ice_check_vf_ready_for_cfg() already contain waiting for reset. New condition in ice_check_vf_ready_for_reset() causing only problems.
