[PATCH iwl-net 0/2] ice: fix DFLT Rx rule handling for promisc and switchdev

From: Petr Oros

Date: Thu Jun 18 2026 - 11:11:02 EST


Two fixes for the uplink default VSI Rx rule (DFLT) on E810 when the
netdev is in IFF_PROMISC.

Patch 1 drops the redundant per-VLAN promisc expansion that exhausts
the FLU pool on a wide VLAN trunk across several PFs.

Patch 2 keeps the DFLT Rx rule across a switchdev teardown instead of
clobbering the promisc state the operator asked for.

Lab tested on E810-C: functional, VLAN isolation, IFF_ALLMULTI
regression, stress/flap and switchdev-toggle suites pass with no AQ
errors, and the FLU pool stays under its ceiling with all four PFs
loaded.

Petr Oros (2):
ice: skip per-VLAN promisc rules when default VSI Rx rule is set
ice: preserve uplink DFLT Rx rule on switchdev release
