From 7a4fa29106d9a38ef005f5ab15d493c259f269c0 Mon Sep 17 00:00:00 2001 From: Yuval Mintz Date: Thu, 14 Dec 2017 15:54:29 +0200 Subject: net: sched: Add TCA_HW_OFFLOAD Qdiscs can be offloaded to HW, but current implementation isn't uniform. Instead, qdiscs either pass information about offload status via their TCA_OPTIONS or omit it altogether. Introduce a new attribute - TCA_HW_OFFLOAD that would form a uniform uAPI for the offloading status of qdiscs. Signed-off-by: Yuval Mintz Acked-by: Jiri Pirko Signed-off-by: David S.
