Will do. Sorry about that.

I was under the impression as well, that s/w lro is moot, if h/w lro was av=
ailable, till one costumer asked for it. Not sure what the use case is.

Thanks
David S.

Hi David,

I know this is not a new topic but a little more descriptive commit-log wou=
ld have been nicer. Also, you should update the manpage reflecting this cha=
nge. i.e. now it also supports software LRO when h/w LRO is disabled.

Do you know of a case where one would want to disable h/w lro and enable s/=
w lro? I guess where you want to free up nic and make cpu do more work?

Cheers,
Hiren
