[PATCH net-next v2] net: phy: broadcom: remove BCM5482 1000Base-BX support

From: Michael Walle
Date: Mon Feb 08 2021 - 18:18:33 EST


It is nowhere used in the kernel. It also seems to be lacking the
proper fiber advertise flags. Remove it.

changes since v1:
- added queue to subject
- reworded 1000BX to 1000Base-BX
