gre: Add Transparent Ethernet Bridging
This patch adds support for Ethernet over GRE encapsulation. This is exposed to user-space with a new link type of "gretap" instead of "gre". It will create an ARPHRD_ETHER device in lieu of the usual ARPHRD_IPGRE. Note that to preserver backwards compatibility all Transparent Ethernet Bridging packets are passed to an ARPHRD_IPGRE tunnel if its key matches and there is no ARPHRD_ETHER device whose key matches more closely.
