Re: [PATCH net] selftests: net: wait for receiver startup in so_txtime.sh

Paolo Abeni wrote:

The mentioned test is failing in slow environments:

# SO_TXTIME ipv4 clock monotonic # ./so_txtime: recv: timeout: Resource temporarily unavailable not ok 1 selftests: net: so_txtime.sh # exit=1

The receiver is started in background and the sender could end-up transmitting the packet before the receiver is ready, so that the later recv times out.

Address the issue explcitly waiting for the socket being bound to the relevant port.
