[PATCH] skge: dont use dev_alloc_skb for rx buffs

Browse Source 
The skge driver was using dev_alloc_skb which reserves space for the
Ethernet header. This unnecessary and it should just use alloc_skb,
also by using GFP_KERNEL during startup it won't run into problems when
a user asks for a huge ring size or mtu and potentially drains the
reserved atomic pool.
