| |
I've found something strange going on in 2.4 kernels - when I run 'netstat -r' I get the routing table from /proc/net/route. The MSS value reported is only 40 bytes, and when I run 'cat /proc/net/route I'm told that the _MTU_ is 40 bytes. I thought the MSS was supposed to be the MTU - 40 bytes, not 40 bytes in total, where the MTU for ethernet is 1500. If I run ifconfig, it reports the correct MTU of 1500 for eth0 and 16463 for lo. This computer has a NetGear FA311 card, and is running 2.4.19-pre7-ac2, though I've also seen this happening on a 2.4.18 kernel.
