Previously, VF recovery from PF-initiated resets required explicit opt-in via auto_reset, leaving VFs non-functional by default after a reset unless the application handled it. This series makes transparent recovery including the restoration of settings the default, and implements some fixes related to the reset path as well.
Patch 1 fixes a regression which prevented promiscuous mode from being disabled before sending the RESET_VF message to the PF during device close. Patch 2 enables the auto_reset and no-poll-on-link-down devargs by default so VFs recover from resets without the need to introduce any reset handling in the application. Patch 3 introduces a new auto_reconfig devarg (on by default) which extends the recovery path to restore unicast and multicast promiscuous state after a reset. Restoration of additional settings such as VLAN filters could be added under the same mechanism in a follow-up series. Patch 4 fixes a minor logging issue.
