====== Adrian's Todo list ======

===== Embedded =====

==== Atheros MIPS ====

  * Fix if_arge.c RX ring handling so mbufs aren't being wasted each time the interface is up/down'ed (PR?)
  * Re-architect the whole phymask mess with if_arge
  * Work with juli@ to optimise if_arge throughput
  * hwpmc mips24k support for sampled/interrupt driven measurement

==== Switch Framework ====

  * Import bits of the switch framework as required (see ray@ and stb)

===== Network =====

  * merge in the netgraph vlan patch to -HEAD (PR?)
  * make sure if_bridge is correctly choosing bridge MACs that don't overlap (PR?)

===== Net80211 =====

  * Figure out a good way to handle fragments, now that r190579 broke fragment handling (as IF_ENQUEUE and IF_DEQUEUE both clear the m_nextpkt chained fragments, leaking fragment mbufs.)
  * Figure out why scan/bgscan actually issues the first scan even though traffic is definitely ongoing
  * In the case of a scan being interrupted, how do we inform any consumers (eg via scan ioctl from userland) that the scan was interrupted, rather than having it simply hang indefinitely.

===== ath / ath_hal =====

  * Tidy up the rate control API - it's very messy and could do with a bi of a sanity check
  * .. then, begin work to merge the rate control stuff back into the net80211 rate control API.
  * Survey/add missing locking surrounding how ieee80211_node entries are handled for nodes that aren't in a node table. (Commit? PR?)
  * Implement if_transmit and handle fragments correctly (see above.)
  * Finish BAR TX handling (which involves correctly debugging node pause/unpause)
  * Reduce the size of the hardware queue when doing non-aggregation - don't just fill it full of non-aggregate frames
  * Teach ath_start() to only allow ~ half of the TX buffers to be allocated before delaying TX - that way space is left over for management frames (eg ADDBA, BAR.)
  * Export the rate control statistics using a command line program or a sysctl which returns the text data - stop doing it via kernel printf()s
  * Correctly handle frames when doing
