Hello all,
Does the TSO offload option works for chained mbufs?
What i mean is, if i have a chain representing a big TCP buffer, and i only
set the first mbuf with
TSO flags and tso_segsz (mss) and L4 size, will that work ? (or only
applied on the first mbuf)
I think that ideally this should work, just like for example, Jumbo frames
are being
splitted into chained mbuf's (other direction)
Thanks
Gal.

This should work indeed.
In a mbuf chain, only the first mbuf carries the flags for the
whole chain.
