Zen Kato has a device which reports the 0xa RF type. The vendor driver
treats this as AL2230S, the same as devices with the AL2230S bit in the POD.

Zen Kato's device has a regulatory domain value of 0x49, which is not an
IEEE 802.11 code and is not even identified in the vendor driver.

Recent versions of the vendor driver don't even look at the regdomain
value any more, and just allow channels 1-11 everywhere. This patch
brings us more in line with that behaviour, by allowing channels 1-11
for regdomains which we don't know about.

Matteo Croce reported Aironet initialization failures. They were caused by
a race in airo. airo finds a free interface name, then initializes the card
and finally registers the interface. Another device may get the same name
in the meantime.
The reason airo gets its name early is to use it in informative printks and
to name the resources it requests. The printks will be just fine without
the interface name and the resources can use the driver's name - that's
what other network drivers do anyway.
One of the talkative functions is setup_card(). It is called once before
registration and can be called later again. Let's have an empty dev->name
during the first call, so it doesn't print the ugly "airo(eth%d)" message.

Add rudimentary check for the case that the page table overflows due to
merging of s/g elements by the IOMMU.  This would have lead to
overwriting of arbitrary memory.

After this change I expect that an offending command will be
unsuccessfully retried until the scsi_device is taken offline by SCSI
core.  It's a border case and not worth to implement a recovery
strategy.

Use a speed probe to determine the speed over 1394b buses and of nodes
which report a link speed less than their PHY speed.

Log the effective maximum speed of newly created nodes in dmesg.

Also, read the config ROM (except bus info block) at the maximum speed
rather than S100.  This isn't a real optimization though because we
still only use quadlet read requests for the entire ROM.

Based on patch "the scheduled removal of RAW1394_REQ_ISO_{SEND,LISTEN}"
from Adrian Bunk, November 20 2006.

This patch also removes the underlying facilities in ohci1394 and
disables them in pcilynx.  That is, hpsb_host_driver.devctl() and
hpsb_host_driver.transmit_packet() are no longer used for iso reception
and transmission.

Since video1394 and dv1394 only work with ohci1394 and raw1394's rawiso
interface has never been implemented in pcilynx, pcilynx is now no
longer useful for isochronous applications.

raw1394 will still handle the request types but will complete the
requests with errors that indicate API version conflicts.
