BTW MSG_ZEROCOPY is enabled only for TCP and UDP, but we allow it to be set on
all, which leads to BROK:
./netstress -z -T sctp
tst_test.c:1096: INFO: Timeout per run is 0h 05m 00s
netstress.c:938: INFO: max requests '3'

safe_net.c:186: BROK: netstress.c:717: setsockopt(3, 1, 60, 0x7fff155701a4, 4) failed: ???
Kind regards,
Petr
