Hello there, | did see some bugs about LSO on OpenSolaris.org: http://bugs.opensolaris.org/bugdatabase/printableBug.do?bug_id=6909685
We are seeing some problems about packets greater than the MTU (using snoop), on e1000 ethernet nics. That can result in big performance impact. So, adding this line to e1000g.conf did solve the issue: lso_enable=0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0; So, i want to understand that... what i did understand from some comments in the bugs database, is that the TCP stack is sending LSO packets for the NIC driver (>MTU), and the NIC is not fragmenting this packets for the correct MTU because it "thinks" the packet is fine. So, disabling LSO in the driver conf (lso_enable=0), the driver is doing the correct handle on the MTU size. Is that correct? Would be nice if somebody on net could give some insights about the concepts behind this. Thanks a lot for your time!
