Yep. That was fixed.
Looks like only one test is failing on s390:
test_synproxy:PASS:./xdp_synproxy --iface tmp1 --single 0 nsec
expect_str:FAIL:SYNACKs after connection unexpected SYNACKs after
connection: actual '' != expected 'Total SYNACKs generated: 1\x0A'

#284/1 xdp_synproxy/xdp:FAIL
#284 xdp_synproxy:FAIL
Summary: 260/1530 PASSED, 31 SKIPPED, 1 FAILED
