Subject: [RFC PATCH net-next 17/22] net: dsa: mt7530: fix port capabilities for MT7988

From: Arınç ÜNAL <arinc.unal@...nc9.com>

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")
