So far the mirred action has dealt with syntax that handles mirror/redirection for netdev. A matching packet is redirected or mirrored to a target netdev. In this patch we enable mirred to mirror to a tc block as well. IOW, the new syntax looks as follows: ... mirred <ingress | egress> <mirror | redirect> [index INDEX] < <blockid BLOCKID> | <dev <devname>> > Examples of mirroring or redirecting to a tc block: $ tc filter add block 22 protocol ip pref 25 \ flower dst_ip 192.168.0.0/16 action mirred egress mirror blockid 22 $ tc filter add block 22 protocol ip pref 25 \ flower dst_ip 10.10.10.10/32 action mirred egress redirect blockid 22 Co-developed-by: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: Jamal Hadi Salim <jhs@mojatatu.com> Co-developed-by: Pedro Tammela <pctammela@mojatatu.com> Signed-off-by: Pedro Tammela <pctammela@mojatatu.com> Signed-off-by: Victor Nogueira <victor@mojatatu.com> Signed-off-by: David S.
