* introducing MSS oddities to segment boundaries. In rare cases where
|

* mss_now != mss_cache, we will request caller to create a small skb
|
||||
* per input skb which could be mostly avoided here (if desired).

* We explicitly want to create a request for splitting write queue tail
|
||||
* to a small skb for Nagle purposes while avoiding unnecessary modulos,
|

* thus all the complexity (cwnd_len is always MSS multiple which we
|
||||
* return whenever allowed by the other factors). Basically we need the
|
||||
* modulo only when the receiver window alone is the limiting factor or
|
||||
* when we would be allowed to send the split-due-to-Nagle skb fully.
