Re: [Linux-decnet-user] More RH7.1 / kernel 2.4 copying woes

Hi,

I am afraid the problem is related to the MTU (Max Transfer Unit) that
Steve's Kernel implementation of DECnet uses. This was set to 230 Bytes
so I had to issue a patch for DAPFS to work with it (BLOCK I/O would fail 
because it needs more that 230 bytes (????)). You can obtain it downloading 
the dapfs patch and applying it.

Hope this helps,

Eduardo Serrat
