[PATCH 0/4] net/iavf: improve VF reset resilience

[Ciara Loftus]

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.
