This patch series update OVS compat layer to handle IPv6 UDP based
tunnels. While doing this various fixes and updates to tunnel code
are also brought in. This series sync OVS tunnel compat codebase upto
latest net branch (commit 9a0fee2b552b1235fb1706ae1fc664ae74573be8).
v3-v4:
Fixed according to comments from Jesse.
v2-v3:
Addressed comments from v2.
Added four patches:
1. To rename HAVE_METADATA_DST
2. iptunnel_xmit starts update.
3. refactore dst code into separate patch.
4. Fix iptunnel_xmit() packet len bug.
v1-v2:
Brocken down patched further to better align the patches
with upstream commit.
There is still patch 14 which has code from multiple commits.
I can break it down further if it help in review process.
