RTEMS 4.9.5 vs 4.10.2 Network Stack

[SAeeD]

As I traced the execution of RTEMS 4.10.2 with a simple TCP client
application on QEMU, I got this experimental:
After setting up a TCP server in PC, I executed the TCP client on Mini2440
and traced the execution. A socket is created with socket descriptor #3.
Every thing seems fine but when calling function "connect", after a long
time hanging on the line 161 of the following context (rtems_syscall.c
where function "connect" if implemented.), an error numbered #116 happens
and I got out of the loop and return -1 as the return value of function
"connect". This is the context:

160    while ((so->so_state & SS_ISCONNECTING) && so->so_error == 0) {
161        error = soconnsleep (so);
162        if (error)
163            break;
164    }
165    if (error == 0) {
166        error = so->so_error;
167        so->so_error = 0;
168    }
169    bad:
170    so->so_state &= ~SS_ISCONNECTING;
171    m_freem (nam);
172    if (error)
173        errno = error;
174    else
175        ret = 0;
176    rtems_bsdnet_semaphore_release ();
177    return ret;

What could be the possible problem? What is the meaning of error #116?

I think I should also mention that when sniffing packets on telnetd
application, Mini2440 (which was running RTEMS 4.10.2) did not respond to
ARP requests from my PC. After I manipulated my PC's ARP table manually,
then Mini2440 didn't respond to my PC's TCP Syn packets so telnetd didn't
work too.

Thanks for any hint
