unknown, probably firmware fault. Now the stall is only cleared on data
transfer errors.

other modules can generate USB descriptors.
- extend the vendor specific request function by one length pointer argument,
because not all descriptors store the length in the first byte. For example
HID descriptors.

Also disable relaxed ordering as recommended by data sheet for
PCI-X devices. For PCI-X BCM5704, set maximum outstanding split
transactions to 0 as indicated by data sheet.
For BCM5703 in PCI-X mode, DMA read watermark should be less than
or equal to maximum read byte count configuration. Enforce this
limitation in DMA read watermark configuration.
chip revision often found in the blades and resulting in interfaces
not sensing carrier signal. Looking at all problem reports it
appears that it only affects some very specific silicon revision
(ASIC (0x57081021); Rev (B2)) and version of the PHY that
supports 1000baseSX-FDX media only. Therefore, narrow the scope of
workaround to combination of that revision and media type. Given
that the first report on this issue is dated back to 2007, there is
not much hope that this issue will ever be properly resolved.
Among affected systems are IBM HS21, Intel SBXD132 and HP BL460c.

Setting the new sysctl MIB "debug.acpi.enable_debug_objects" to a non-zero
value enables us to print Debug object when something is written to it.
- Allow users to disable interpreter slack mode. Setting the new tunable
"debug.acpi.interpreter_slack" to zero disables some workarounds for common
BIOS mistakes and enables strict ACPI implementations by the specification.
pmc_flush_logfile is now non-blocking and just ask the kernel
to shutdown the file. From that point, no more data is
accepted by the log thread and when the last buffer is flushed
the file is closed.
This will remove a deadlock between pmcstat asking for
flush while it cannot flush the pipe itself.

does not generate excessive interrupts any more so we don't need
to have two copies of interrupt handler.
While I'm here remove two STAT_PUT_IDX register accesses in LE
status event handler. After r204539 msk(4) always sync status LEs
so there is no need to resort to reading STAT_PUT_IDX register to
know the end of status LE processing. Just trust status LE's
ownership bit.
countdown timer register. The timer resolution may vary among
controllers but the value would be represented by core clock
cycles. msk(4) will automatically computes number of required clock
cycles from given micro-seconds unit.
The default interrupt holdoff timer value is 100us which will
ensure less than 10k interrupts under load. The timer value can be
changed with dev.mskc.0.int_holdoff sysctl node.
Note, the interrupt moderation is shared resource on dual-port
controllers so you can't use separate interrupt moderation value
for each port. This means we can't stop interrupt moderation in
driver stop routine. Also have msk_tick() reclaim transmitted Tx
buffers as safety belt. With this change there is no need to check
missing Tx completion interrupt in watchdog handler, so remove it.
full-duplex. Previously msk(4) used to allow flow-control on

partner is capable of handling it.
While I'm here use IFM_OPTIONS instead of using IFM_GMASK to check
optional flags of link.
