>Description:
The wg_rekey test case of the net/if_wg/t_misc:wg_rekey test
is failing for me on real amd64 hardware. For example:
http://www.gson.org/netbsd/bugs/build/amd64-baremetal/2020/2020.10.14.18.48.05/test.html#net_if_wg_t_misc_wg_rekey

I ran a bisection, and it identified this commit as the point
where the problem started:
2020.09.07.01.14.42 riastradh src/sys/net/if_wg.c 1.54
Logs:
http://www.gson.org/netbsd/bugs/build/amd64-baremetal/commits-2020.09.html#2020.09.07.01.14.42
The test fails in most runs (but not quite all of them) on real
hardware, but does not fail on the qemu based testbeds. Perhaps
it's a question of multiprocessor vs. uniprocessor.
