This commit breaks build of some 3rd party wireless module we use here
(because sizeof(sa->sa_data) no longer works and needs to use
sa_data_min)
With that said I guess it really is a dependency on the arp_req_get
overflow, so probably necessary evil, and I don't think we explicitly
pretend to preserve APIs for 3rd party modules so this is probably
fine... The new warnings that poped up (and were reported in other
messages) a probably worth checking though.


That aside no particular problem actually running this, so--
Tested 5d69d611e74d ("Linux 5.10.211-rc1") on:
- arm i.MX6ULL (Armadillo 640)
- arm64 i.MX8MP (Armadillo G4)

No obvious regression in dmesg or basic tests:
