[SRU][Q/N/J][PATCH 0/1] ubuntu_kselftests:_net/net:gre_gso.sh failing (LP: #2136820)

[Kuba Pawlak]

BugLink: https://bugs.launchpad.net/bugs/2136820

rarely gre_gso.sh fails with socat getting killed by signal 15. Note that in the
log below two "exiting on signal 15" are ok. The first one should not be there.

This is most likely timing issue and can be mitigated by increasing timeout for
socat from 1 to 3 seconds.
