This patch set:
- Adds support for GSO and GRO for ip6ip6 and ip4ip6
- Add support for FOU and GUE in IPv6
- Support GRE, ip6ip6 and ip4ip6 over FOU/GUE
- Fixes ip6_input to deal with UDP encapsulations
- Some other minor fixes
v2:
- Removed a check of GSO types in MPLS
- Define GSO type SKB_GSO_IPXIP6 and SKB_GSO_IPXIP4 (based on input
from Alexander)
- Don't define GSO types specifally for IP6IP6 and IP4IP6, above
fix makes that uncessary
- Don't bother clearing encapsulation flag in UDP tunnel segment
(another item suggested by Alexander).
v3:
- Address some minor comments from Alexander
v4:
- Rebase on changes to fix IP TX tunnels
- Fix MTU issues in ip4ip6, ip6ip6
- Add test data for above
Tested:
Tested a variety of case, but not the full matrix (which is quite
large now). Most of the obivous cases (e.g. GRE) work fine. Still
some issues probably with GSO/GRO being effective in all cases.
