- Fix nexus_setup_intr() abuse of setting up multiple IRQs in one go. Calling
arm_setup_irqhandler() in loop is bogus, as there's just one cookie given
from the caller and it is overwritten in each iteration so that only the
last handler's cookie value prevails.
- Proper intr masking/unmasking handling: the IRQ source is masked at PIC level
only after the last handler has been removed from the list.

The old logic padded the device name out but assumed the unit number was one digit
long; this fails for things like SATA devices which (for me) begin at ad10.
Assemble the full device name in a temporary buffer and then calcluate padding
based on that string.
isn't fixed to only open the network device once and not do a open
and close dance on every file access; the firmwares of newer sparc64
machines perform an auto-negotiation with every open which in turn
causes netbooting to take horribly long if we open and close the
device over and over again.

login sessions timeout during moderate TTY activity. An example of
where this might occur is where a pending write to the terminal is
occurring while sshd(8) is shutting down the TTY after a TCP timeout.

memory-mapped config access. Add a workaround for these systems by
checking the first function of each slot on bus 0 using both the
memory-mapped config access and the older type 1 I/O port config access.
If we find a slot that is only visible via the type 1 I/O port config
access, we flag that slot. Future PCI config transactions to flagged
slots on bus 0 use type 1 I/O port config access rather than memory mapped
config access.
detaching that when the USB is pulled out forcibly during the driver is
running background scan, a page fault can be occurred even if we called
usb_rem_task() when detaching. It looks like a kind of races.
This allows the location of the configuration data to be relocated
within the filesystem containing it. A nullfs mount is used in order
to achieve this.
