New Revision: 279492
URL: https://svnweb.freebsd.org/changeset/base/279492
Log:
AR8327: Disable energy-efficient ethernet support in the PHYs.
I noticed that openwrt/linux does this, citing "instability", so
until they figure out why I'm going to disable it here as well.
Tested:
* QCA AP135 - QCA955x SoC + AR8327 switch.
