eth1 on linux 2.4.25 from ELDK 3.1.1 becomes slowly when is pinged by great packets

[Igor Marnat]

Hi list!
I tried to work with kernel 2.4.25 from ELDK 3.1.1 from Denx. My board is 
PPChameleon EVB (PPC 405 EP). First, the kernel even didn't compile as is for 
this architecture, I've forced to made changes (see the patch below) to be 
able to build the kernel for this board. Now I'm experiencing the following 
problem: I've inited both interfaces (eth0 and eth1). When I ping eth1 with 
small packet (less that 2k), it works fine. When I ping eth1 with the packets 
of size greater that 2k, time of responce becomes about n * 1000 
milliseconds. I.e., ping writes me: 

3008 bytes from 90.0.0.139: icmp_seq=1 ttl=64 time=3001 ms
3008 bytes from 90.0.0.139: icmp_seq=2 ttl=64 time=3002 ms
...
3008 bytes from 90.0.0.139: icmp_seq=6 ttl=64 time=3003 ms
3008 bytes from 90.0.0.139: icmp_seq=7 ttl=64 time=3003 ms


Sometimes it is 2000 ms, sometimes it is 1000 ms, but it's always like this. 
After it was one time pinged by the great packets, it'll responce in such a 
fashion allways, even when is pinged by the smapll packets. Once crashed, it 
is crashed till it is reinited. To make it work normally once again, I do:
#ifconfig eth1 down
#ifconfig eth1 up

and it helps, i.e. after reinitialization eth1 work normally. Eth0 works fine 
anyway with pings of any sizes. What is the status of PPChameleon in ELDK 
3.1.1? Is it supported in general? Any ideas or suggestions? I've searched 
the archives and tried the patches of Matt Porter (of Mar 3, about jumbo 
packets size), but it didn't help. 

Regards,
Igor Marnat

You must be using old code (probably the version that came with  ELDK
3.1.1?).  Please  fetch  the  current  code from CVS; see commit "Fix
problems with second ethernet interface on 405EP".

Wolfgang, thank you!=20
I've renewed the kernel from CVS and it works much better now.=20
By the way, the driver for PPChameleonEVB is presented in linuxppc_2_4_deve=

module only and is not presented in linux-2.4 module of CVS (there miss the=

Thank you again, regards,

Fine.

Yes, this is intentional. The linux-2.4 module  is  a  more  or  less
frozen  version  of  linux  kernel  version 2.4.4 which we keep alife
because some of our customers continue to use this in their projects.
