addition of SerDes support. According to the docs, the 5706C and 5708C
phys are supposed to use the same MII model that is separate from the
SerDes parts, but the 5706C actually uses the MII model of the SerDes
parts. To fix this, readd the old 5706C entry to miidevs and add a
special check in brgphy_probe() for phys that match the 5706C ID. If
the phy is supported by the gentbi(4) driver, then it's a SerDes phy, so
we fail the probe and let gentbi(4) grab it. Otherwise, it's a 5706C phy,
so we let brgphy(4) grab it.

Remove the device_printf() in iwi_ioctl() and replace with this:
/*
* wait until pending iwi_cmd() are completed, to avoid races
* that could cause problems.
*/
while (sc->flags & IWI_FLAG_BUSY)
msleep(sc, &sc->sc_mtx, 0, "iwiioctl", hz);
This at least prevents what has become an almost systematic failure for my
system, presumably due to a previous iwi_cmd() not complete yet by the
time iwi_ioctl() is called.
It has been pointed to my attention that the real problem could be
calling ieee80211_ioctl() with the lock held. If that is true,
there might still be a possibility for a race condition e.g. an
interrupt coming while the ioctl is sleeping.
Need to investigate further on what changes are required to release
the lock before calling ieee80211_ioctl
+ do not release the dma-ble region used for downloading firmware.
This should fix the problems that some people were seeing, due to
memory becoming too fragmented which prevented subsequent allocations
of a suitable contiguous region of memory;
+ document the firmware format and usage in if_iwivar.h
+ use a loop to allocate the four tx rings, instead of replicating
the body of the loop.
+ add debugging code IWI_LOCK_ASSERT() to detect missing locks.
These only do a printf, and should go away once we figure out why
the driver sometimes freezes the system due to a (yet unidentified)
race condition.
+ add a device_printf() in iwi_ioctl() in certain conditions
(see comment in the code). This helps preventing the race condition
mentioned above, and makes the system survive. This printf will
also go away once fixing this bug is completed.
