eth: remove neterion/vxge
The last meaningful change to this driver was made by Jon in 2011.
As much as we'd like to believe that this is because the code is
perfect the chances are nobody is using this hardware.
Because of the size of this driver there is a nontrivial maintenance
cost to keeping this code around, in the last 2 years we're averaging
more than 1 change a month. Some of which require nontrivial review
effort, see commit 877fe9d49b74 ("Revert "drivers/net/ethernet/neterion/vxge:
Fix a use-after-free bug in vxge-main.c"") for example.
Let's try to remove this driver. In general, IMHO, we need to
establish a clear path for shedding dead code. It will be hard
to unless we have some experience trying to delete stuff.
