ice: VXLAN and Geneve TC support
Add definition for VXLAN and Geneve dummy packet. Define VXLAN and Geneve type of fields to match on correct UDP tunnel header. Parse tunnel specific fields from TC tool like outer MACs, outer IPs, outer destination port and VNI. Save values and masks in outer header struct and move header pointer to inner to simplify parsing inner values. There are two cases for redirect action: - from uplink to VF - TC filter is added on tunnel device - from VF to uplink - TC filter is added on PR, for this case check if redirect device is tunnel device VXLAN example: - create tunnel device ip l add $VXLAN_DEV type vxlan id $VXLAN_VNI dstport $VXLAN_PORT \ dev $PF - add TC filter (in switchdev mode) tc filter add dev $VXLAN_DEV protocol ip parent ffff: flower \ enc_dst_ip $VF1_IP enc_key_id $VXLAN_VNI action mirred egress \ redirect dev $VF1_PR Geneve example: - create tunnel device ip l add $GENEVE_DEV type geneve id $GENEVE_VNI dstport $GENEVE_PORT \ remote $GENEVE_IP - add TC filter (in switchdev mode) tc filter add dev $GENEVE_DEV protocol ip parent ffff: flower \ enc_key_id $GENEVE_VNI dst_ip $GENEVE1_IP action mirred egress \ redirect dev $VF1_PR Signed-off-by: Michal Swiatkowski <michal.swiatkowski@linux.intel.com> Tested-by: Sandeep Penigalapati <sandeep.penigalapati@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
