Hi I installed the following driver. http://www.f.csce.kyushu-u.ac.jp/~shigeaki//software/freebsd-nfe.html Before I had the nve driver which was unstable on this server and on a prior server in both cases causing either spontaneous reboot or just a crash when under load. So far touchwood the nfe driver has stayed up and running at almost 3 days uptime and has had some stress. I know the driver supports device polling which I have chosen not to use yet as I wanted to see initially if it was more stable in its default mode. But what I want to know is the following if possible please. My ifconfig output below. nfe0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 options=8<VLAN_MTU> inet x.x.x.x netmask 0xffffff00 broadcast x.x.x.x inet x.x.x.x netmask 0xffffffff broadcast x.x.x.x ether x media: Ethernet autoselect (1000baseTX <full-duplex>) status: active 1 - is there a man page for nfe anywhere? 2 - does it support hardware checksum I remember reading it does but from ifconfig output it appears to not be in use so if it does support it how do I enable it? 3 - same with TOS? 4 - how do I enable jumbo frames if it supports it? 5 - is it safe to use with zero copy sockets? 6 - I currently have both net.isr.direct and mpsafenet disabled is this driver safe to use on them? Thanks Chris
