Re: Network changes between 4.x and 5.1RC3 ?
Thanks for the replies. I have tried:
* turning off ipf
* turning off hardware checksum, I just did
"ifconfig bge1 -ip4csum -tcp4csum -udp4csum -tso4"
* few more sysctl settings, kern.sbmax kern.somaxkva net.inet.ip.ifq.maxlen
* Check SSL versions, try a couple of different versions.
Not entirely sure there has been any difference. Tried booting old kernel, but
alas, "mount" is too new and won't talk to the older kernel. Without being about
to mount anything, it isn't so useful :)
As for the large transfers that stall, I did notice that 200M transfers are
fine, but 500M transfers are not. Tempted to try sizes and work out exactly what
size it dies on..
I will keep poking anyway.

I have seen something loosely similar on an old OpenSolaris box with ipf
(here is the common denominator with NetBSD). Turning ipf off fixed the
stalls and eventually i figured that it must have been a bug in ipf
"state" handling code - when the rules were written without using the
"state", everything was going normal.
