Subject: [PATCH v4 net-next 0/6] net: ethernet: ti: am65-cpsw: Fix set channel operation

Hi,

This contains a critical bug fix for the recently merged suspend/resume
support [1] that broke set channel operation. (ethtool -L eth0 tx <n>)

As there were 2 dependent patches on top of the offending commit [1]
first revert them and then apply them back after the correct fix.

[1] fd23df72f2be ("net: ethernet: ti: am65-cpsw: Add suspend/resume support")

cheers,
-roger

Changelog:
v4:
- move am65_cpsw_nuss_ndev_add_tx_napi() earlier to avoid declaration.
- print error and error out if soft RESET failed in
  am65_cpsw_nuss_ndo_slave_open()
- move struct 'am65_cpsw_host *host' where 'common' is defined.

v3:
- revert offending commit before applying the updated patch.
- drop optimization patch to be sent separately.

v2:
- Fix build warning
 drivers/net/ethernet/ti/am65-cpsw-nuss.c:562:13: warning: variable 'tmo' set but not used [-Wunused-but-set-variable]
