> AM65 CPSW h/w supports Enhanced Scheduled Traffic (EST – defined
> in P802.1Qbv/D2.2 that later got included in IEEE 802.1Q-2018)
> configuration. EST allows express queue traffic to be scheduled
> (placed) on the wire at specific repeatable time intervals. In
> Linux kernel, EST configuration is done through tc command and
> the taprio scheduler in the net core implements a software only
> scheduler (SCH_TAPRIO). If the NIC is capable of EST configuration,
> user indicate "flag 2" in the command which is then parsed by
> taprio scheduler in net core and indicate that the command is to
> be offloaded to h/w. taprio then offloads the command to the
> driver by calling ndo_setup_tc() ndo ops. This patch implements
> ndo_setup_tc() as well as other changes required to offload EST
> configuration to CPSW h/w
