The psock_snd test sends and recievs packets over loopback, but the
parameter lo.accept_local is disabled by default, this test will
fail with Resource temporarily unavailable:
sudo ./psock_snd.sh
dgram
tx: 128
rx: 142
./psock_snd: recv: Resource temporarily unavailable
So enable the parameter lo.accept_local in psock_snd test.
