It's been there for quite some time.

For just messing about, might it be possible to tweak the socket
buffer sizes and tcp_tso_win_divisor to kludge things for a short
while? Couldn't ship that way certainly, but assuming

I'm having an issue with TSO right vs. hardware that can't take the
maximum segment size sent from the stack. I've been told that the
maximum packet size that can be sent to the hardware today is 64k, but
my hardware can only take 32k in certain modes per queue due to hardware
limitations. I have
