Subject: [PATCH net-next v4] net: ti: icssg_prueth: add TAPRIO offload support

From: Roger Quadros <rogerq@...com>

ICSSG dual-emac f/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() to offload EST configuration to ICSSG.

Changes from v3 to v4:
*) Rebased on the latest next-20231005 linux-next.
*) Addressed Roger and Vinicius' comments and moved all the validations to
   emac_taprio_replace() API.
*) Modified emac_setup_taprio() API to use switch case based on taprio->cmd
   and added emac_taprio_destroy() and emac_taprio_replace() APIs.
*) Modified the documentation of structs / enums in icssg_qos.h by using
   the correct kdoc format.

Changes from v2 to v3:
*) Rebased on the latest next-20230928 linux-next.
*) Retained original authorship of the patch.
*) Addressed Roger's comments and modified emac_setup_taprio() and
   emac_set_taprio() APIs accordingly.
*) Removed netif_running() check from emac_setup_taprio().
*) Addressed Vinicius' comments and added check for MIN and MAX cycle time.
*) Added check for allocation failure of est_new in emac_setup_taprio().

Changes from v1 to v2:
*) Rebased on the latest next-20230921 linux-next.
*) Dropped the RFC tag as merge window is open now.
*) Splitted this patch from the switch mode series [v1].
*) Removed TODO comment as asked by Andrew and Roger.
*) Changed Copyright to 2023 as asked by Roger.
