commit 7c97bc0128b2eecc703106112679a69d446d1a12 upstream
The pause settings reported by the PHY should also be applied to the GMII port
status override otherwise the switch will not generate pause frames towards the
link partner despite the advertisement saying otherwise.
Fixes: 246d7f773c13 ("net: dsa: add Broadcom SF2 switch driver")
