@ -184,14 +184,14 @@ tcp_frto - INTEGER
F-RTO is an enhanced recovery algorithm for TCP retransmission
timeouts. It is particularly beneficial in wireless environments
where packet loss is typically due to random radio interference
rather than intermediate router congestion. FRTO is sender-side
rather than intermediate router congestion. F-RTO is sender-side
only modification. Therefore it does not require any support from
the peer, but in a typical case, however, where wireless link is
the local access link and most of the data flows downlink, the
faraway servers should have FRTO enabled to take advantage of it.
faraway servers should have F-RTO enabled to take advantage of it.
If set to 1, basic version is enabled. 2 enables SACK enhanced
F-RTO if flow uses SACK. The basic version can be used also when
SACK is in use though scenario(s) with it exists where FRTO
SACK is in use though scenario(s) with it exists where F-RTO
interacts badly with the packet counting of the SACK enabled TCP
flow.

The "enviromental" rules for authors of any new tc actions are:
1) If you stealeth or borroweth any packet thou shalt be branching
from the righteous path and thou shalt cloneth.
For example if your action queues a packet to be processed later
or intentionaly branches by redirecting a packet then you need to
clone the packet.
There are certain fields in the skb tc_verd that need to be reset so we
avoid loops etc. A few are generic enough so much so that skb_act_clone()
resets them for you. So invoke skb_act_clone() rather than skb_clone()
2) If you munge any packet thou shalt call pskb_expand_head in the case
someone else is referencing the skb. After that you "own" the skb.
You must also tell us if it is ok to munge the packet (TC_OK2MUNGE),
this way any action downstream can stomp on the packet.
3) dropping packets you dont own is a nono. You simply return
TC_ACT_SHOT to the caller and they will drop it.
The "enviromental" rules for callers of actions (qdiscs etc) are:
*) thou art responsible for freeing anything returned as being
TC_ACT_SHOT/STOLEN/QUEUED. If none of TC_ACT_SHOT/STOLEN/QUEUED is
returned then all is great and you dont need to do anything.
Post on netdev if something is unclear.
