Johannes Berg 05c914fe33 mac80211: use nl80211 interface types
There's really no reason for mac80211 to be using its
own interface type defines. Use the nl80211 types and
simplify the configuration code a bit: there's no need
to translate them any more now.

Christian Lamparter 7cb770729b p54: move eeprom code into common library
Both p54pci and p54usb uses a good chunk of device specific code to
get the data from the device's eeprom into the drivers memory.

So, this patch reduces the code size and will it make life easier if
someone wants to implement ethtool eeprom dumping features.

Christian Lamparter 4e416a6f49 p54: enhance firmware parser to reduce memory waste
This patch greatly reduces one of biggest memory waste in the driver.

The firmware headers provides the right values for extra head-/tailroom
and mtu size which are usually much lower than the old hardcoded ones.

Christian Lamparter 0c25970dc1 p54pci: increase ring buffer index counter when skipping
I'm afraid, I forgot to add the following lines to
7262d59366 ("p54pci: rx tasklet refactoring").

These changes are necessary to ensure loop termination.

Christian Lamparter 7262d59366 p54pci: rx tasklet refactoring
This patch moves the all of p54pci's receiver code out of the
bloated interrupt handler routine and into a less critical tasklet.

Christian Lamparter 32ddf07185 p54: rename prism54xyz -> p54xyz
It's been a long time, but fullmac prism54 driver is still around...
I think we should rename every prism54* in order to avoid some
confusion about "what is actually what" in the future ;-).

Johannes Berg 36d6825b91 mac80211: let drivers wake but not start queues
Having drivers start queues is just confusing, their ->start()
callback can block and do whatever is necessary, so let mac80211
start queues and have drivers wake queues when necessary (to get
packets flowing again right away.)
