Hi Ankit,

Can you be more explicit?
Where do you type that? As a build command? In the UART console?
What is 8008? a socket port?

I'd like to debug that issue, but have limited experience debugging network stack. Switching to 4.11 is not an option as it involves too much code to port. I have a JTAG and can break into RTEMS code. I read but didn't find any printf in mbuf.h nor if.h.
