One of the machines on our network spits out the following (constantly): xl0: no memory for rx list -- packet dropped! It is of course unreachable through the network. This popped up on 4.2-RELEASE one single time, then went away after a reboot. Now, on 4.3-RELEASE, it was running fine till ab

Re: size of data to ip layer from tcp layer

2001-05-11 Thread Barney Wolff
This is not quite true. MSS can be set arbitrarily by the other end of the connection, and if the receiver is on a link with bigger MTU, or just wants things in big batches, it can set MSS up to 65535. It's up to your own end to check both MSS and the link MTU and decide what size segs to send do

mbuf organization in case 65536 bytes of data.

Hi, My doubt is how data will be organized in buffers in case we want to transmit large amount of data. My doubt is regarding the organization of mbufs in case we want to transmit the maximum ip datagram size. In the normal case data is stored in clusters for data size greater than 208 bytes.

I have run into two issues, that I find really, really annoying. This is in FreeBSD 4.3 and 5.x. Bot machines are on a local (non-switched) segment (it works the same with a switch, but taking that out proves it is not the switch causing the problem). Primus -- The first is that when you
