From f36fe1c498c8959812415c57b683abaa4527dec5 Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Wed, 17 Jan 2018 11:46:48 +0100 Subject: net: sched: introduce block mechanism to handle netif_keep_dst calls Couple of classifiers call netif_keep_dst directly on q->dev. That is not possible to do directly for shared blocke where multiple qdiscs are owning the block. So introduce a infrastructure to keep track of the block owners in list and use this list to implement block variant of netif_keep_dst.
