Subject: [PATCH] net: tsn: add an netlink interface between kernel and
application layer
This patch provids netlink method to configure the TSN protocols hardwares.
TSN guaranteed packet transport with bounded low latency, low packet delay
variation, and low packet loss by hardware and software methods.
The three basic components of TSN are:
1. Time synchronization: This was implement by 8021AS which base on the
IEEE1588 precision Time Protocol. This is configured by the other way
in kernel.
8021AS not included in this patch.
2. Scheduling and traffic shaping and per-stream filter policing:
This patch support Qbv/Qci.
3. Selection of communication paths:
This patch not support the pure software only TSN protocols(like Qcc)
but hardware related configuration.
TSN Protocols supports by this patch: Qbv/Qci/Qbu/Credit-base Shaper(Qav).
This patch verified on NXP ls1028ardb board.
Will add more protocols in the future.
