Hi, folks,

Do you know how to increase the FIFO (both input and output) packet queue
limits (Default is 100 packets) to, say, 1000 packets ?

I mean, where is the file that defines this default limit ?

Also, this seems to be the protocol independent queue. I want to increase all
possible internal queues that a packet may pass through a Redhat 9 Linux that
acts as a router. Is there also a network card queue ("ifconfig eth0
txqueuelen 1000"? but what is the receiving side "ifconfig eth0 rxqueuelen
1000" -- tried, but incorrect).

Thanks!

If what you want to do is increase tcp speed, especially by increasing the
tcp window size to allow slow acks for distant links, see this thread:
