This adds a few improvements and fixes for vxlan support.
The following two patches are already backported to openwrt-1907 and
can be dropped after bumping to the next point release:
0011-vxlan-fix-udp-checksum-control.patch
0012-vxlan-bump-and-change-to-PKG_RELEASE.patch
The other two patches won't be backported and have to be kept until
we move up to 20.xx:
0013-vxlan-remove-mandatory-peeraddr.patch
0014-vxlan-add-capability-for-multiple-fdb-entries.patch
