Hi,

While working on TSO based solution I faced the following two questions:

1.
is there a maximum pkt_len to be used with TSO?, e.g. let's say if seg_sz
is 1400 can the entire segmented pkt be 256K (higer than 64K) ?, then the
driver gets a list of chanined mbufs while the first mbuf is set to TSO
offload.

2.
I wonder, Is there a specific reason why TSO is supported only for IXGBE
and not for IGB ? the 82576 NIC supports TSO though.
Is it due to a kind of tecnical barrier or is it because of priorities?

It will be great if someone from the forum could address this.

Thanks,
Sim
