From 8d1a77f974ca61d39afa5bf0aeab210525d31475 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Wed, 20 Dec 2017 12:35:19 -0500 Subject: net: sch: api: add extack support in tcf_block_get This patch adds extack support for the function tcf_block_get which is a common used function in the tc subsystem. Callers which are interested in the receiving error can assign extack to get a more detailed information why tcf_block_get failed.
