act_skbedit: skbedit queue mapping for receive queue
Add support for skbedit queue mapping action on receive
side. This is supported only in hardware, so the skip_sw
flag is enforced. This enables offloading filters for
receive queue selection in the hardware using the
skbedit action. Traffic arrives on the Rx queue requested
in the skbedit action parameter. A new tc action flag
TCA_ACT_FLAGS_AT_INGRESS is introduced to identify the
traffic direction the action queue_mapping is requested
on during filter addition. This is used to disallow
offloading the skbedit queue mapping action on transmit
side.
Example:
$tc filter add dev $IFACE ingress protocol ip flower dst_ip $DST_IP\
action skbedit queue_mapping $rxq_id skip_sw
