Re: [lwip-users] lwIP hangs on transfers with many short packets

[Tyrel Newton]

How is your system configured?

- xilkernel or standalone
- socket or raw API
- emaclite or temac

Btw, don't expect much help from the Xilinx forums. Also, don't much 
faith in the quality of the application-layer code that Xilinx provides, 
including xilkernel and the associated sys_arch layer for lwIP and the 
lwIP netif drivers for the emaclite and the temac.
