Subject: [PATCH net-next 2/3] net: phy: broadcom: Fix RXC/TXC auto disabling
Date:   Fri, 12 Feb 2021 12:57:20 -0800

When support for optionally disabling the TXC was introduced, bit 2 was
used to do that operation but the datasheet for 50610M from 2009 does
not show bit 2 as being defined. Bit 8 is the one that allows automatic
disabling of the RXC/TXC auto disabling during auto power down.
