> Subject: [PATCH v1] gso: fix marking TCP checksum flag in TCP segments
> 
> Large TCP packets which are marked with PKT_TX_TCP_SEG flag are
> segmented and the flag is cleared in the resulting segments, however, the
> segments checksum is not updated. It is therefore required to set the
> PKT_TX_TCP_CKSUM flag in each TCP segment in order to mark for the
> sending driver the need to update the TCP checksum before transmitting the
> segment.
