Basically, this piece looks relatively easy. Namespace is already
available on the dst entry via device and the device is safe to
dereferrence. Compare it with one of a searcher and skip entry if
appropriate.

The only exception is ip_rt_frag_needed. So, add namespace parameter to it.

Stephen Hemminger d5ce8a0e97 [IPV4] fib_trie: avoid rescan on dump
This converts dumping (and flushing) of large route tables form O(N^2)
to O(N). If the route dump took multiple pages then the dump routine
gets called again. The old code kept track of location by counter, the
new code instead uses the last key.

This is a really big win ( 0.3 sec vs 12 sec) for big route tables.

One side effect is that if the table changes during the dump, then the
last key will not be found, and we will return -EBUSY.

Bruno Randolf 6d91e1d808 ath5k: configure backoff for IBSS beacon queue
in "11.1.2.2 Beacon generation in an IBSS" the IEEE802.11 standard says, each
STA should... "b) Calculate a random delay uniformly distributed in the range
between zero and twice aCWmin × aSlotTime,".

configure cwmin and cwmax of the beacon queue in IBSS mode according to this.
unfortunately beacon backoff does not work reliably yet, so i suspect we have a
problem somewhere else, since the same settings (and similar beacon timer
configuration) work for madwifi.

Bruno Randolf 036cd1ec03 ath5k: use SWBA to detect IBSS HW merges
use SWBA (software beacon alert) interrupts to keep track of the next beacon
time und check if a HW merge (automatic TSF update) has happened on every
received beacon with the same BSSID.

this is necessary because the atheros hardware will silently update the local
TSF in IBSS mode, but not its beacon timers. if the TSF is ahead of the beacon
timers no beacons are sent until the timers wrap around (typically after about
1 minute).

this solution is not very nice, since we have to look into every beacon, but
there is apparently no other way to detect HW merges.

update ath5k_beacon_update_timers() for better beacon timer calculation in a
variety of situations. most important is the possibility to call it with the
timestamp of a received beacon, when we detected that a HW merge has happened
and we need to reconfigure the beacon timers based on that.

we call this from the mac80211 callback reset_tsf now instead of beacon_update,
and there will be more use of it in the next patch.

Michael Buesch 1f7d87b0ec b43: Fix MAC control and microcode init
This zeros out all microcode related memory before loading
the microcode.

This also fixes initialization of the MAC control register.
The _only_ place where we overwrite the contents of the MAC control
register is at the beginning of b43_chip_init().
All other places must do read() -> mask/set -> write() to not
overwrite existing bits.

This also adds a longer delay for waiting for the microcode
to initialize itself. It seems that the current timeout is sufficient
on all available devices, but there's no real reason why we shouldn't
wait for up to one second. Slow embedded devices might exist.
Better safe than sorry.
