Parallel port in 405GP?

Parallel port in 405GP?

[v.sudeep]

Hi !!!

I am a newbie to embedded and linux. And I want to know if the IBM Walnut
405GP board has a parallel port. From the meagre documentation that I have
read, I find nothing to suggest that it has. Am I right on this one ??

Thanks in advance.

hi, Wojciech
can you send the patch?
did you free skbuffs from the irq handler or somewhere else?

when i run netperf (snapshot) test using the 100Mbps connection, this
test eats all the available RAM. the /proc/meminfo shows that most of the
used
memory at that point is been held by internal kernel structures (Slab).
