VALIDATE_MASK(eth_mask->h_source) is checked twice in a row in bcmgenet_validate_flow(). Add VALIDATE_MASK(eth_mask->h_dest) instead. Fixes: 3e370952287c ("net: bcmgenet: add support for ethtool rxnfc flows") Cc: stable@vger.kernel.org Signed-off-by: Denis Efremov <efremov@linux.com> --- I'm not sure that h_dest check is required here, it's only my guess.
