From e99a986161918ac2e1c7f3b5e1d9f61e5d5d32ce Mon Sep 17 00:00:00 2001 From: Doug Berger Date: Wed, 22 Jun 2022 20:02:04 -0700 Subject: [PATCH] net: dsa: bcm_sf2: force pause link settings 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.
