Subject: [PATCH net-next 17/30] net: dsa: mt7530: fix port capabilities for MT7988

From: Arınç ÜNAL <[email protected]>

On the switch on the MT7988 SoC, there are only 4 PHYs. That's port 0 to 3.
Set the internal phy cases to '0 ... 3'.

There's no need to clear the config->supported_interfaces bitmap before
reporting the supported interfaces as all bits in the bitmap will already
be initialized to zero when the phylink_config structure is allocated.
There's no code that would change the bitmap beforehand. Remove it.

Fixes: 110c18bfed41 ("net: dsa: mt7530: introduce driver for MT7988 built-in switch")

Either there is a user visible bug and in that case the patch needs to
go to the 'net' tree, or you need to drop the 'Fixes' tag.

Also, 2 separate logical changes => 2 patches please. Thanks.
