====================
WireGuard bug fixes and cleanups

I've been working through some personal notes and also the whole git
repo history of the out-of-tree module, looking for places where
tradeoffs were made (and subsequently forgotten about) for old kernels.
The first two patches in this series clean up those. The first one does
so in the self-tests and self-test harness, where we're now able to
expand test coverage by a bit, and we're now cooking away tests on every
commit to both the wireguard-linux repo and to net-next. The second one
removes a workaround for a skbuff.h bug that was fixed long ago.
Finally, the last patch in the series fixes in a bug unearthed by newer
Qualcomm chipsets running the rmnet_perf driver, which does UDP GRO.
