The mirror/redirect action is extended to forward to a traffic class on the device if the traffic class index is provided in addition to the device's ifindex. Example: # tc filter add dev eth0 protocol ip parent ffff: prio 1 flower\ dst_ip 192.168.1.1/32 ip_proto udp dst_port 22\ skip_sw action mirred ingress redirect dev eth0 tclass 1 v2: Introduced is_tcf_mirred_tc() helper function to check if the rule is supported in current offloaders. Removed the additional definitions for max number of TCs and its bitmask and replaced their usages with existing defines in linux/netdevice.h.

The patch implements functions and admin queue commands needed to support cloud filters in the driver and adds cloud filters to configure these tc-flower filters. The only action supported is to redirect packets to a traffic class on the same device. # tc qdisc add dev eth0 ingress # ethtool -K eth0 hw-tc-offload on # tc filter add dev eth0 protocol ip parent ffff:\ prio 1 flower dst_mac 3c:fd:fe:a0:d6:70 skip_sw\ action mirred ingress redirect dev eth0 tclass 0 # tc filter add dev eth0 protocol ip parent ffff:\ prio 2 flower dst_ip 192.168.3.5/32\ ip_proto udp dst_port 25 skip_sw\ action mirred ingress redirect dev eth0 tclass 1 # tc filter add dev eth0 protocol ipv6 parent ffff:\ prio 3 flower dst_ip fe8::200:1\ ip_proto udp dst_port 66 skip_sw\ action mirred ingress redirect dev eth0 tclass 1 Delete tc flower filter: Example: # tc filter del dev eth0 parent ffff: prio 3 handle 0x1 flower # tc filter del dev eth0 parent ffff: Flow Director Sideband is disabled while configuring cloud filters via tc-flower and until any cloud filter exists. Unsupported matches when cloud filters are added using enhanced big buffer cloud filter mode of underlying switch include: 1. source port and source IP 2. Combined MAC address and IP fields. 3. Not specifying L4 port These filter matches can however be used to redirect traffic to the main VSI (tc 0) which does not require the enhanced big buffer cloud filter support. v3: Cleaned up some lengthy function names. Changed ipv6 address to __be32 array instead of u8 array. Used macro for IP version. Minor formatting changes. v2: 1. Moved I40E_SWITCH_MODE_MASK definition to i40e_type.h 2. Moved dev_info for add/deleting cloud filters in else condition 3. Fixed some format specifier in dev_err logs 4. Refactored i40e_get_capabilities to take an additional list_type parameter and use it to query device and function level capabilities. 5. Fixed parsing tc redirect action to check for the is_tcf_mirred_tc() to verify if redirect to a traffic class is supported. 6. Added comments for Geneve fix in cloud filter big buffer AQ function definitions. 7. Cleaned up setup_tc interface to rebase and work with Jiri's updates, separate function to process tc cls flower offloads. 8. Changes to make Flow Director Sideband and Cloud filters mutually exclusive.
