DSA tag protocol support #93010

yangbolu1991 · 2025-07-11T09:44:52Z

This PR is to support DSA tag protocol in DSA core driver. Also added NXP NETC tag protocol driver, and enabled on NXP i.MX943 as an example to verify.

There is a hal dependency: zephyrproject-rtos/hal_nxp#575
Thanks a lot.

Attached dsa sample log.
