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
