Subject: [PATCH iproute2-next 1/9] uapi: add definitions for preemptible traffic classes in mqprio and taprio
Date: Mon,  3 Apr 2023 13:52:37 +0300	[thread overview]
Message-ID: <20230403105245.2902376-2-vladimir.oltean@nxp.com> (raw)
In-Reply-To: <20230403105245.2902376-1-vladimir.oltean@nxp.com>

Get the definitions from the linux/pkt_sched.h which allow us to add
netlink attributes to the TCA_OPTIONS of mqprio and taprio that specify
which traffic classes are express and which are preemptible.
