controller with Card Read Host Controller. These controllers are
multi-function devices and have the same ethernet core of
JMC250/JMC260. Starting from REVFM 5(chip full mask revision)
controllers have the following features.
o eFuse support
o PCD(Packet Completion Deferring)
o More advanced PHY power saving
Because these controllers started to use eFuse, station address
modified by driver is permanent as if it was written to EEPROM. If
you have to change station address please save your controller
default address to safe place before reprogramming it. There is no
way to restore factory default station address.
Many thanks to JMicron for continuing to support FreeBSD.

allow the child atkbd device to reuse that IRQ resource instead of
reallocating the same IRQ from the parent bus inside the atkbd driver.
- Don't allocate a shared IRQ for the atkbd driver. For AT keyboard
devices on an ISA bus the IRQ is not shareable. Instead, the bus driver
should mark the IRQ shareable if the bus supports shared IRQs.
- Don't identify child devices until after the atkbdc device itself has
attached.
delete the IRQ resource from the psmcpnp device completely.
- Don't allocate the IRQ resource shared. It is not a shareable interrupt
on ISA. The bus driver can set RF_SHAREABLE if the IRQ is actually
shareable on a non-ISA bus.
- Avoid side-effect assignments in if statements when possible.
- Don't use ! to check for NULL pointers, explicitly check against NULL.
- Explicitly check error return values against 0.
- Don't use INTR_MPSAFE for interrupt handlers with only filters as it is
meaningless.
- Remove unneeded function casts.
function always returned the nominal frequency instead of current frequency
because we use RDTSC instruction to calculate difference in CPU ticks, which
is supposedly constant for the case. Now we support cpu_get_nominal_mhz()
for the case, instead. Note it should be just enough for most usage cases
because cpu_est_clockrate() is often times abused to find maximum frequency
of the processor.
There is no need to use an atomic operation at structure initialization
time.
Note that the file changed is not connected to the build at this time.

Prior to this change, the addressing method wasn't getting set, and
so the LUN field could be set incorrectly in some instances.
This fix should allow for LUN numbers up to 16777215 (and return an error
for anything larger, which wouldn't fit into the flat addressing model).

This bug manifested itself after repeated device arrivals and
departures. The root of the problem was that the last entry in the
reply array wasn't initialized/allocated. So every time we got
around to that event, we had a bogus address.
There were a couple more problems with the code that are also fixed:
- The reply mechanism was being treated as sequential (indexed by
sc->replycurindex) even though the spec says that the driver
should use the ReplyFrameAddress field of the post queue
descriptor to figure out where the reply is. There is no
guarantee that the reply descriptors will be used in sequential
order.
- The second word of the reply post queue descriptor wasn't being
checked in mps_intr_locked() to make sure that it wasn't
0xffffffff. So the driver could potentially come across a
partially DMAed descriptor.
- The number of replies allocated was one less than the actual
size of the queue. Instead, it was the size of the number of
replies that can be used at one time. (Which is one less than
the size of the queue.)
mps.c: When initializing the entries in the reply free
queue, make sure we initialize the full number that
we tell the chip we have (sc->fqdepth), not the
number that can be used at any one time (sc->num_replies).
When allocating replies, make sure we allocate the
number of replies that we've told the chip exist,
not just the number that can be used simultaneously.
Use the ReplyFrameAddress field of the post queue
descriptor to figure out which reply is being
referenced. This is what the spec says to do, and
the spec doesn't guarantee that the replies will be
used in order.
Put a check in to verify that the reply address passed
back from the card is valid. (Panic if it isn't, we'll
panic when we try to deference the reply pointer in any
case.)
In mps_intr_locked(), verify that the second word of the
post queue descriptor is not 0xffffffff in addition to
verifying that the unused flag is not set, so we can
make sure we didn't get a partially DMAed descriptor.
Remove references to sc->replycurindex, it isn't needed
now.
mpsvar.h: Remove replycurindex from the softc, it isn't needed now.

AX88772 controllers. ASIX added a new feature for AX88178/AX88772
controllers which allows combining multiple TX frames into a single
big frame. This was to overcome one of USB limitation where it
can't generate more than 8k interrupts/sec which in turn means USB
ethernet controllers can not send more than 8k packets per second.
Using ASIX's feature greatly enhanced TX performance(more than 3~4
times) compared to 7.x driver. However it seems r184610 removed
boundary checking for buffered frames which in turn caused
instability issues under certain conditions. In addition, using
ASIX's feature triggered another issue which made USB controller
hang under certain conditions. Restarting ethernet controller
didn't help under this hang condition and unplugging and replugging
the controller was the only solution. I believe there is a silicon
bug in TX frame combining feature on AX88178/AX88772 controllers.
To address these issues, reintroduce the boundary checking for both
AX88178 and AX88772 after copying a frame to USB buffer and do not
use ASIX's multiple frame combining feature. Instead, use USB
controller's multi-frame transmit capability to enhance TX
performance as suggested by Hans[1].
This should fix a long standing axe(4) instability issues reported
on AX88772 and AX88178 controllers. While I'm here remove
unnecessary TX frame length check since upper stack always
guarantee the size of a frame to be less than MCLBYTES.
Special thanks to Derrick Brashear who tried numerous patches
during last 4 months and waited real fix with patience. Without
this enthusiastic support, patience and H/W donation I couldn't fix
it since I was not able to trigger the issue on my box.

as an association ID is set any scan is supposed to be a background scan.
This implies that the firmware will switch back to the associated channel
after a certain threshold, though, we are not notified about that. We
currently catch this case by a timer which will reset the firmware after
a 'scan timeout', though, upper layers are not notified about that and
will simply hang until manual intervention. Fix this by resetting the
firmware's knowledge about any association on RUN -> ASSOC and
