Yield to other senders or receivers on the same netisr if the current TCP
stream has sent certain amount of segments (currently 4) and is going to
burst more segments.  sysctl net.inet.tcp.fairsend could be used to tune
how many segements are allowed to burst.  For TSO capable devices, their
TSO aggregate size limit could also affect the number of segments allowed
to burst.  Set net.inet.tcp.fairsend to 0 will allow single TCP stream to
burst as much as it wants (the old TCP sender's behaviour).

"Fairsend" is performed at the places that do not affect segment sending
during congestion control:
- User requested output path
- ACK input path

Measured improvement in the following setup:

C (e3-1230, w/ HT enabled), 82574L
The performance stats are gathered from 'systat -if 1'

When A runs 8 TCP senders to C and 8 TCP receivers from B, sending
performance are same ~975Mbps, however, the receiving performance before
this commit stumbles between 670Mbps and 850Mbps; w/ "fairsend" receiving
performance stays at 981Mbps.

When A runs 16 TCP senders to C and 16 TCP receivers from B, sending
performance are same ~975Mbps, however, the receiving performance before
this commit goes from 960Mbps to 980Mbps; w/ "fairsend" receiving
performance stays at 981Mbps stably.

When there are more senders and receivers running on A, there is no
noticable performance difference on either sending or receiving between
non-"fairsend" and "fairsend", because senders are no longer being able
to do continuous large burst.

"Fairsend" also improves Jain's fairness index between various amount of
senders (8 ~ 128) a little bit (sending only tests).

  streams are running on the same GigE NIC).
  TSO large burst has following drawbacks on a single TX queue, even on
  the devices that are multiple TX queues capable:
  o  Delay other senders' packet transmission quite a lot.
  o  Has negative effect on TCP receivers, which sends ACKs.
  o  Cause buffer bloat in software sending queues, whose upper limit is
     based on "packet count".
  o  Packet scheduler's decision could be less effective.
  On the other hand, TSO large burst could improve CPU usage.
- Improve fairness between multiple TX queues on the devices that are
  multiple TX queues capable but only fetch data on TSO large packet
  boundary instead of TCP segment boundary.

Drivers could supply their own TSO aggregation size limit.  If driver
does not set it, the default value is 6000 (4 segments if MTU is 1500).

Sepherosa Ziehau [Fri, 11 Jan 2013 05:31:30 +0000 (13:31 +0800)]
if: Multiple TX queue support step 1 of many; introduce ifaltq subqueue

Put the plain queue information, e.g. queue header and tail, serializer,
packet staging scoreboard and ifnet.if_start schedule netmsg etc. into
its own structure (subqueue).  ifaltq structure could have multiple of
subqueues based on the count that drivers can specify.

Subqueue's enqueue, dequeue, purging and states updating are protected
by the subqueue's serializer, so for hardwares supporting multiple TX
queues, contention on queuing operation could be greatly reduced.

The subqueue is passed to if_start to let the driver know which hardware
TX queue to work on.  Only the related driver's TX queue serializer will
be held, so for hardwares supporting multiple TX queues, contention on
driver's TX queue serializer could be greatly reduced.

Bunch of ifsq_ prefixed functions are added, which is used to perform
various operations on subqueues.  Commonly used ifq_ prefixed functions
are still kept mainly for the drivers which do not support multiple TX
queues (well, these functions also ease the netif/ convertion in this
step :).

All of the pseudo network devices under sys/net are converted to use the
new subqueue operation.  netproto/802_11 is converted too.  igb(4) is
converted to use the new subqueue operation, the rest of the network
drivers are only changed for the if_start interface modification.

For ALTQs which have packet scheduler enabled, only the first subqueue
is used (*).

(*) Whether we should utilize multiple TX queues if ALTQ's packet scheduler
is enabled is quite questionable.  Mainly because hardware's multiple TX
queue packet dequeue mechanism could have negative impact on ALTQ's packet
scheduler's decision.
