| Subject: net: dsa: bcm_sf2: force pause link settings |
| |
| From: Doug Berger <opendmb@gmail.com> |
| |
| 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") |
