Hi all,
I'm not fully sure what's purpose of this code in tcp_write_xmit:
if (skb->len < limit) {
unsigned int trim = skb->len % mss_now;
if (trim)
limit = skb->len - trim;
}
Is it used to make sure we send only multiples of mss_now here and leave
the left-over into another skb? Or does it try to make sure that
tso_fragment result honors multiple of mss_now boundaries when snd_wnd
is the limitting factor? For latter IMHO this would be necessary:
if (skb->len > limit)
limit -= limit % mss_now;
