Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue
Tony Nguyen says: ==================== Intel Wired LAN Driver Updates 2023-04-04 (ice) This series contains updates to ice driver only. Simei adjusts error path on adding VF Flow Director filters that were not releasing all resources. Lingyu adds setting/resetting of VF Flow Director filters counters during initialization. * '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue: ice: Reset FDIR counter in FDIR init stage ice: fix wrong fallback logic for FDIR ==================== Link: https://lore.kernel.org/r/20230404172306.450880-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
