From 776fe19953b0e0af00399e50fb3b205101d4b3c1 Mon Sep 17 00:00:00 2001 From: Michal Swiatkowski Date: Thu, 5 Oct 2023 09:33:30 -0700 Subject: ice: block default rule setting on LAG interface When one of the LAG interfaces is in switchdev mode, setting default rule can't be done. The interface on which switchdev is running has ice_set_rx_mode() blocked to avoid default rule adding (and other rules). The other interfaces (without switchdev running but connected via bond with interface that runs switchdev) can't follow the same scheme, because rx filtering needs to be disabled when failover happens. Notification for bridge to set promisc mode seems like good place to do that.

Most places in the code got it right, but one line was still wrong. Fix this one location for easy backports to stable. An in-progress patch fixes the defines to "standard" and will be applied as part of the regular -next process sometime after this one.
