X-Git-Tag: v22.03.0-rc1~125
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a5995272ede4f493deaccf7f50c7df4b9cca3e23;p=openwrt%2Fstaging%2Fhauke.git

ath79: fix link for long cables with OCEDO Raccoon

The OCEDO Raccoon had significant packet-loss with cables longer than 50
meter. Disabling EEE restores normal operation.

Also change the ethernet config to reduce loss on sub-1G links.
