====================
wireguard updates and fixes for 6.13

This tiny series (+3/-2) fixes one bug and has three small improvements.

1) Fix running the netns.sh test suite on systems that haven't yet
   inserted the nf_conntrack module.

2) Remove a stray useless function call in a selftest.

3) There's no need to zero out the netdev private data in recent
   kernels.

4) Set the TSO max size to be GSO_MAX_SIZE, so that we aggregate larger
   packets. Daniel reports seeing a 15% improvement in a simple load and
   suggested the speedups would be even better in more complex loads.
