[PATCH v6 0/5] add dsa switch support for ar9331

[Oleksij Rempel]

changes v6:
- rebase against net-next

changes v5:
- remote support for port5. The effort of using this port is
  questionable. Currently, it is better to not use it at all, then
  adding buggy support.
- remove port enable call back. There is nothing what we actually need
  to enable.
- rebase it against v5.5-rc1 

changes v4:
- ag71xx: ag71xx_mac_validate fix always false comparison (&& -> ||)
- tag_ar9331: use skb_pull_rcsum() instead of skb_pull().
- tag_ar9331: drop skb_set_mac_header()

changes v3:
- ag71xx: ag71xx_mac_config: ignore MLO_AN_INBAND mode. It is not
  supported by HW and SW.
- ag71xx: ag71xx_mac_validate: return all supported bits on
  PHY_INTERFACE_MODE_NA

changes v2:
- move Atheros AR9331 TAG format to separate patch
- use netdev_warn_once in the tag driver to reduce potential message spam
- typo fixes
- reorder tag driver alphabetically 
- configure switch to maximal frame size
- use mdiobus_read/write
- fail if mdio sub node is not found
- add comment for post reset state
- remove deprecated comment about device id
- remove phy-handle option for node with fixed-link
- ag71xx: set 1G support only for GMII mode

This patch series provides dsa switch support for Atheros ar9331 WiSoC.
As side effect ag71xx needed to be ported to phylink to make the switch
driver (as well phylink based) work properly.
