AM6442: Tsn support

Mustafa Filiz

Part Number: AM6442

Hello,

we are willing to use Am6442 TSN features in system.
There is detailed information in the link https://software-dl.ti.com/processor-sdk-linux/esd/AM64X/latest/exports/docs/linux/Foundational_Components/PRU-ICSS/Linux_Drivers/PRU_ICSSG_Ethernet.html#introduction

Still we cant be sure about ICSSG TSN.
Does ICSSG ethernet ports support TSN on linux ?
The webpage mention about TSN but nothing about 802.1p or 802.1Qav.

Does ICSSG support theese features ? Does ICSSG ethernet ports supports TSN ?

Thank you
