Subject[PATCH net] net: phylink: check for SFP bus presence in phylink_expects_phy
Date
When an SFP bus is present, we don't expect a PHY to be attached
directly from the MAC driver, it will be handled by phylink at SFP
attach time.

Fixes: 653a180957a8 ("net: phylink: add phylink_expects_phy() method")

This was tested on dwmac_socfpga, following discussion here [1]
