First 4 patches are more-or-less cleanups/preparations.
Patch 5 was sent to me/contributed off-list by Mohammad, who wants 32-bit kernels to run TCP-AO.
Patch 6 is a workaround/fix for slow VMs. Albeit, I can't reproduce the issue, but I hope it will fix netdev flakes for connect-deny-* tests.
Hm, could be a coincidence but we did hit:
# not ok 55 # error 381[unsigned-md5.c:24] Failed to add a VRF: -17 # not ok 56 # error 383[unsigned-md5.c:33] Failed to add a route to VRF: -22: Key was rejected by service

Yeah, I think I've seen that previously on netdev as well, but quite rarely. Let me take a look and see why adding a VRF table sometimes fails with EEXIST.
in the first run after this got queued. But the retry worked:

oooh another run, another (different) flake: https://netdev-3.bots.linux.dev/vmksft-tcp-ao-dbg/results/710181/11-key-mana...
Yeah, this is related to this very patch set. Some more work clearly needed :-)
Thanks, Dmitry
