If we do end up using GRE for ethernet tunneling, there's some work that
needs to be done. For one, ip_gre in its current form would need a certain
amount of hacking for tunneling ethernet frames instead of IPv4/IPv6 as
it does now. We might as rename it to plain 'gre' and move it out of
net/ipv4/ to net/core/ or something while we're at it.
Now that I think about this a bit more, there may be a potential
If the payload of GRE is an ethernet frame, which GRE 'Protocol Type'
(i.e., ethertype) would that be?
I doubt anyone has defined an ethertype which would be used to
transmit full ethernet frames inside an ethernet header, so this would
likely need to be some special value..
(Another solution for this problem space is obviously L2TP, which is
also rather widely supported..)
