what does the 'tso' mean in the networking subsystem?

["rwen2012" <rwen2012@xxxxxxxxx>]

HI, All

 

I see many 'tso' in the source code, but don't know what does it mean.

Could anyone tell me what is that and how does it use?

Thanks.

/* This must be invoked the first time we consider transmitting

static int tcp_init_tso_segs(struct sock *sk, struct sk_buff *skb, unsigned int mss_now)
{
 int tso_segs = tcp_skb_pcount(skb);

 

 if (!tso_segs ||
     (tso_segs > 1 &&
      tcp_skb_mss(skb) != mss_now)) {
  tcp_set_skb_tso_segs(sk, skb, mss_now);
  tso_segs = tcp_skb_pcount(skb);
 }
 return tso_segs;
}
