> stmmac reception handler calls stmmac_rx_vlan() to strip the vlan > before calling napi_gro_receive(). > > The function assumes VLAN tagged frames are always tagged with > 802.1Q protocol, and assigns ETH_P_8021Q to the skb by hard-coding > the parameter on call to __vlan_hwaccel_put_tag() without checking > the actual VLAN tag. > > This causes packets not to be passed to the VLAN slave if it was > created with 802.1AD protocol (ip link add link eth0 eth0.100 type > vlan proto 802.1ad id 100). > > This fix only strips the VLAN tag for 802.1Q tagged > protocols. 802.1AD frames will be handled later by skb_vlan_untag(). > > Signed-off-by: Elad Nachman <el...@gilat.com> Giuseppe and Alexandre, please review this patch.
