Re: [Ltib] PowerPC: Build fs_enet as module

[Nirmala]

Hi Stuart,
The kernel (2.6.25) is from kernel.org . Please see my earlier thread 
for more info:
http://lists.gnu.org/archive/html/ltib/2009-05/msg00044.html

In fact We did some u-boot code changes to make the second interface 
work. Now both eth0 and eth1 are enabled and works fine.
However we have some performance issue while running SIP calls through 
asterisk in out embedded system.
for some extent we nailed it down to the network inface problem , so to 
debug issue we need to build Ethernet driver as a module through ltib. 
as i mentioned earlier , building fs_enet fails with below errors, I 
would appreciate if you could guide me in building interface driver as 
module.

Thank You
Nirmala
