3426950e9c Update the list of devices supported by the FTDI driver. It might be
that the wrong UART reference clock will be used for a few of the IDs.
It is currently not possible to figure that out because the Linux FTDI
driver detects this run-time and not compile time based on the bcdDevice
field of the USB device descriptor. Some of the ID's in usbdevs are not
sorted according to the product ID value. Please feel free to fix this.
I'm out of my xemacs magic today.

fffbec8618 Migrate the 802.11n ath_hal_chaintxdesc() API to use a buffer/segment

This removes the last reference to ds_data in the TX path outside of

46634305f4 Migrate the ath_hal_filltxdesc() API to take a list of buffer/seglen values.
The existing API only exposes 'seglen' (the current buffer (segment) length)
with the data buffer pointer set in 'ds_data'.  This is fine for the legacy
DMA engine but it won't work for the EDMA engines.

The EDMA engine has a significantly different TX descriptor layout.

* The legacy DMA engine had a ds_data pointer at the same offset in the
  descriptor for both TX and RX buffers;
* The EDMA engine has no ds_data for RX - the data is DMAed after the
  descriptor;
* The EDMA engine has support for 4 TX buffer/segment pairs in the TX
  DMA descriptor;
* The EDMA TX completion is in a different FIFO, and the driver will
  'link' the status completion entry to a QCU by a "QCU ID".
  I don't know why it's just not filled in by the hardware, alas.

So given that, here are the changes:

* Instead of directly fondling 'ds_data' in ath_desc, change the
  ath_hal_filltxdesc() to take an array of buffer pointers as well
  as segment len pointers;
* The EDMA TX completion status wants a descriptor and queue id.
  This (for now) uses bf_state.bfs_txq and will extract the hardware QCU
  ID from that.
* .. and this is ugly and wasteful; it should change to just store
  the QCU in the bf_state and save 3/7 bytes in the process.

Now, the weird crap:

* The aggregate TX path was using bf_state->bfs_txq for the TXQ, rather than
  taking a function argument.  I've tidied that up.
* The multicast queue frames get put on a software TXQ and then that is
  appended to the hardware CABQ when appropriate.  So for now, make sure
  that bf_state->bfs_txq points at the CABQ when adding frames to the
  multicast queue.
* .. but the multicast queue TX path for now doesn't use the software
  queue and instead
  (a) directly sets up the descriptor contents at that point;
  (b) the frames on the vap->avp_mcastq are then just appended wholesale
      to the CABQ.
  So for now, I don't have to worry about making the multicast path
  work with aggregation or the per-TID software queue. Phew.

What's left to do:

* I need to modify the 11n ath_hal_chaintxdesc() API to do the same.
  I'll do that in a subsequent commit.
* Remove bf_state.bfs_txq entirely and store the QCU as appropriate.
* .. then do the runtime "is this going on the right HWQ?" checks using
  that, rather than comparing pointer values.

Tested on:

* AR9280 STA/AP
* AR5416 STA/AP

7a27d904bd Minor style nit:
Use the interface number from the USB interface descriptor
like in the other USB serial drivers. These numbers are not
supposed to be different, though in theory they can. Make sure
that the driver then uses the interface number given by the USB
descriptor, and not the logical index of the USB stack.

For the future:
Whenever the term "index" is used in the USB code, it refers to
a number computed by the USB stack.
Whenever the term "number" is used in the USB code, it refers to
a number in a USB descriptor.

b5ba3bdb25 Support multiple interface devices. The driver had previously hardcoded
support for only the first port, but the CP2105 can have multiple ports.
Although this allowed the first port to mostly work on multi port devices,
there could be issues with this arrangement.

Update the man page to reflect support for both ports and the CP2105.

2db99100a4 Improve the handling of static DMA buffers that use non-default memory
attributes (currently just BUS_DMA_NOCACHE):
- Don't call pmap_change_attr() on the returned address, instead use
  kmem_alloc_contig() to ask the VM system for memory with the requested
  attribute.
- As a result, always use kmem_alloc_contig() for non-default memory
  attributes, even for sub-page allocations.  This requires adjusting
  bus_dmamem_free()'s logic for determining which free routine to use.
- For x86, add a new dummy bus_dmamap that is used for static DMA
  buffers allocated via kmem_alloc_contig().  bus_dmamem_free() can then
  use the map pointer to determine which free routine to use.
- For powerpc, add a new flag to the allocated map (bus_dmamem_alloc()
  always creates a real map on powerpc) to indicate which free routine
  should be used.

Note that the BUS_DMA_NOCACHE handling in powerpc is currently #ifdef'd out.
I have left it disabled but updated it to match x86.

a6e829596d Fix an issue that crept in with the previous descriptor tidyup.
When forming aggregates, the last descriptor was now not being
correctly setup - instead, the "setuplasttxdesc" call was being
handed the first descriptor in the last subframe, rather than the
last descriptor in the last subframe.

This showed up as "bad series0 hwrate" messages, as the final
descriptor just didn't have any of the rate control information
squirreled away.

o Introduce new lle flag LLE_LINKED, which marks an entry that
