From 0b44b593a78e39b2843c80a1a2d58670a0d5e76f Mon Sep 17 00:00:00 2001 From: John Crispin Date: Sat, 4 Apr 2015 06:10:03 +0000 Subject: [PATCH] kernel: switch to upstream This driver is upstream since 2012 (commit: a8e510f682f), so switch to it and remove own sources. Also place it under "Network Devices" menu together with other phy drivers.
