Merge branch 'cpsw-add-MQPRIO-and-CBS-Qdisc-offload'

Ivan Khoronzhuk says:

====================
net: ethernet: ti: cpsw: add MQPRIO and CBS Qdisc offload

This series adds MQPRIO and CBS Qdisc offload for TI cpsw driver.
It potentially can be used in audio video bridging (AVB) and time
sensitive networking (TSN).

Patchset was tested on AM572x EVM and BBB boards. Last patch from this
series adds detailed description of configuration with examples. For
consistency reasons, in role of talker and listener, tools from
patchset "TSN: Add qdisc based config interface for CBS" were used and
can be seen here: https://www.spinics.net/lists/netdev/msg460869.html

Based on net-next/master

v5..v4:
- corrected typo of "am57xx" board name, no functional changes

v4..v3:
 - nothing, just rebase

v3..v2:
 - corrected typo of "shaper" word, no functional changes

v2..v1:
 - changed name cpsw.txt on ti-cpsw.txt
 - changed name cpsw_set_tc() on cpsw_set_mqprio()
