Subject: [PATCH] net: ethernet: marvell: skge: remove incorrect conflicting PCI ID

The ID 1186:4302 is matched by both r8169 and skge. The same device ID
should not be in more than one driver, because in that case, which
driver is used is unpredictable. I downloaded the latest drivers for
all hardware revisions of the D-Link DGE-530T from D-Link's website,
and the only drivers which contain this ID are Realtek drivers.
Therefore, remove this device ID from skge.

In the kernel bug report which requested addition of this device ID,
someone created a patch to add the ID to skge. Then, it was pointed
out that this device is an "r8169 in disguise", and a patch was created
to add it to r8169. Somehow, both of these patches got merged. See the
link below.
