From 42f39036cda808d3de243192a2cf5125f12f3047 Mon Sep 17 00:00:00 2001 From: Victor Nogueira Date: Tue, 19 Dec 2023 15:16:23 -0300 Subject: net/sched: act_mirred: Allow mirred to block 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 [index INDEX] < | > > 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 Signed-off-by: Jamal Hadi Salim Co-developed-by: Pedro Tammela Signed-off-by: Pedro Tammela Signed-off-by: Victor Nogueira Signed-off-by: David S.
