This series of patches is the first half of the backport of the
Linux kernel upstream ERSPAN feature support.
The first patch does some cleanup of unsupported kernel code. The
remaining patches in the series begin the backport of the actual
ERSPAN code.
As part of the ERSPAN backport it was necessary to fixup the current
out of tree GRE and IP tunneling support by pulling in code from
the upstream Linux kernel. There was a great deal of infrastructure
missing so much of this patch series is actually devoted to making
sure the proper IPV4 tunneling code is pulled in from the upstream
kernel.
Currently the series only builds on kernels <= 4.9. A future patch
will enable builds on kernels greater than 4.9.
Please ignore this patch series - we've fixed a few things so I will
repost a V2 next week.
Thanks,
