Subject: [PATCH] ptts: fix tipcTS failure in case of latency
The 'ptts' test keeps failed when testing under high traffic with some
network latency. This is because the 'tipcTS' server side doesn't wait
long enough at its 'select()' call, just 1s+ and gets timeout. The
time variable is also not re-initiated after the 1st timeout, so the
next attempts just return shortly i.e. timeout = 0:
./tipcTS -v
...
Received on 0 sockets in subtest 6, expected 2
Received on 0 sockets in subtest 6, expected 2
Received on 0 sockets in subtest 6, expected 2
===>Finished SubTest 7: received 0 msgs of sz -1 at 2 sockets (40 per
socket)
TEST FAILED Received wrong number of multicast messages
The commit fixes the issue by increasing the timeout value to 3s and also
re-initiating it correctly.
