Code Issues Releases Activity

Add support for Dlink DL10022 to the ed driver. This is a mii part

Browse Source 
bolted to a ne-2000 chip.  This is necessary for the NetGear FA-410TX
and other cards.

This also requires you add mii to your kernel if you have an ed driver
configured.

This code will result in a couple of timeout messages for ed on the
impacted cards.  Additional work will be needed, but this does work
right now, and many people need these cards.
