selftests: fix poll error in udpgro.sh
The test program udpgso_bench_rx always invokes the poll() syscall with a timeout of 10ms. If a larger timeout is specified via the command line, udpgso_bench_rx is supposed to do multiple poll() calls till the timeout is expired or an event is received. Currently the poll() loop errors out after the first invocation with no events, and may causes self-tests failure alike: failed GRO with custom segment size ./udpgso_bench_rx: poll: 0x0 expected 0x1 This change addresses the issue allowing the poll() loop to consume all the configured timeout. Fixes: ada641ff6ed3 ("selftests: fixes for UDP GRO") Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
