VERSION DETAILS

SUMMARY

I found a problem in which the client would become frozen when the server crashed within the function delay_test(). I added a poll() call prior to the read to exit the program when the data was not available on the FD. I added the poll call in the WAITING loop right before this code:

rx_len = read(eth->intf.sock_fd,
eth->frm.rx_buffer,
eth->params.f_size_total);
