This patch series enables configuring cloud filters in i40e
using the tc-flower classifier. The classification function
of the filter is to match a packet to a traffic class. cls_flower is
extended to offload classid to hardware. Hardware traffic classes
are identified using classid values reserved in the range :ffe0 - :ffef.
The cloud filters are added for a VSI and are cleaned up when
the VSI is deleted. The filters that match on L4 ports needs
enhanced admin queue functions with big buffer support for
extended fields in cloud filter commands.
Example:
# tc qdisc add dev eth0 ingress
# ethtool -K eth0 hw-tc-offload on
Match Dst IPv4,Dst Port and route to TC1:
# tc filter add dev eth0 protocol ip parent ffff: prio 1 flower\
dst_ip 192.168.1.1/32 ip_proto udp dst_port 12000\
skip_sw hw_tc 1
# tc filter show dev eth0 parent ffff:
filter pref 1 flower chain 0
filter pref 1 flower chain 0 handle 0x1 hw_tc 1
eth_type ipv4
ip_proto udp
dst_ip 192.168.1.1
dst_port 12000
skip_sw
in_hw
v5: Hardware traffic class based on reserved classid values.
Changes to align with Jiri's filter-block series. i40e code
cleanup based on Shannon's comments.
