pkt_sched: Fix sch_sfq vs tcf_bind_filter oops
Since there was added ->tcf_chain() method without ->bind_tcf() to sch_sfq class options, there is oops when a filter is added with the classid parameter. Fixes commit 7d2681a6ff4f9ab5e48d02550b4c6338f1638998 netdev thread: null pointer at cls_api.c Signed-off-by: Jarek Poplawski <jarkao2@gmail.com> Reported-by: Franchoze Eric <franchoze@yandex.ru> Signed-off-by: David S.
