Does anyone has experience about what's the processor speed requirement for dealing with networking application(ethernet, WLAN) protocol in embedded linux?
This is based on your requirement. If you want the throughput is very high, you need some powerful CPU. Ask you chip supplier the CPU LAN port performance, then you can select. Embedded Linux is not the most important problem about the Speed Requirement.

Some advice, Freescale(ori Moto) has the MPC8XX or MPC82XX, they are powerful. You can check the performance in the DataSheet.
Some MIPS and Intel CPU are also good at network dealing. But the most important is that almost no one can do wired speed!
In fact, we need a MCU can deal with network protocol with minimum processor speed. Can a ARM7 MCU operate at 50Mhz and intergate with ethernet MAC SOC able to do that?
