c2078f8dc4 tc: flower: Allow *_mac options to accept a mask
* The argument to src_mac and dst_mac may now take an optional mask
  to limit the scope of matching.
* This address is is documented as a LLADDR in keeping with ip-link(8).
* The formats accepted match those already output when dumping flower
  filters from the kernel.

Example of use of LLADDR with and without a mask:

tc qdisc add dev eth0 ingress
tc filter add dev eth0 protocol ip parent ffff: flower indev eth0 \
	src_mac 52:54:01:00:00:00/ff:ff:00:00:00:01 action drop
tc filter add dev eth0 protocol ip parent ffff: flower indev eth0 \
	src_mac 52:54:00:00:00:00/23 action drop
tc filter add dev eth0 protocol ip parent ffff: flower indev eth0 \
	src_mac 52:54:00:00:00:00 action drop

b2a1f740aa tc: flower: document that *_ip parameters take a PREFIX as an argument.
* The argument to src_ip, dst_ip, enc_src_ip and enc_dst_ip take an
  optional prefix length which is used to provide a mask to limit the scope
  of matching.
* This is documented as a PREFIX in keeping with ip-route(8).

Example of uses of IPv4 and IPv6 prefixes

bb9b63b18e tc/cls_flower: Classify packet in ip tunnels
Introduce classifying by metadata extracted by the tunnel device.
Outer header fields - source/dest ip and tunnel id, are extracted from
the metadata when classifying.

For example, the following will add a filter on the ingress Qdisc of shared
vxlan device named 'vxlan0'. To forward packets with outer src ip
11.11.0.2, dst ip 11.11.0.1 and tunnel id 11. The packets will be
forwarded to tap device 'vnet0':

$ tc filter add dev vxlan0 protocol ip parent ffff: \
    flower \
      enc_src_ip 11.11.0.2 \
      enc_dst_ip 11.11.0.1 \
      enc_key_id 11 \
      dst_ip 11.11.11.1 \
    action mirred egress redirect dev vnet0

cfcabf18d8 tc: flower: Add skip_{hw|sw} support
On devices that support TC flower offloads, these flags enable a filter to be
added only to HW or only to SW. skip_sw and skip_hw are mutually exclusive
flags. By default without any flags, the filter is added to both HW and SW,
but no error checks are done in case of failure to add to HW.
With skip-sw, failure to add to HW is treated as an error.

Here is a sample script that adds 2 filters, one with skip_sw and the other
with skip_hw flag.

   # add ingress qdisc
   tc qdisc add dev enp0s9 ingress

   # enable hw tc offload.
   ethtool -K enp0s9 hw-tc-offload on

   # add a flower filter with skip-sw flag.
   tc filter add dev enp0s9 protocol ip parent ffff: flower \
	   ip_proto 1 indev enp0s9 skip_sw \
	   action drop

   # add a flower filter with skip-hw flag.
   tc filter add dev enp0s9 protocol ip parent ffff: flower \
	   ip_proto 3 indev enp0s9 skip_hw \
	   action drop
