system have been attached, but no later. This ensures that we do
not explore ohci or uhci busses before the companion echi controller
has been initialised, so it should fix the problem of multi-speed
USB devices getting attached as USB 1 devices first and then
re-attached as USB 2.
Some further changes are needed on architectures that do not currently
allow hooks to be inserted before configure_final() - alpha, ia64,
powerpc and sparc64. On these architectures the exploration will
now be delayed until the usb kthread runs.

currently copy the entire packet a couple bytes to get the packet aligned

in the window between the beginning of panic() and entering the debugger,
it's possible to receive interrupts. If we receive an interrupt, don't
preempt if panicstr != NULL, as the system is in the process of failing, and
the preempting thread is likely to stumble over the failure. The typical
scenario is during the printf() in panic() prior to entering the debugger,
but when running with a slower console type such as serial console.
It could be that the panic string should be passed to the debugger to print,
so that it can run from the debugger's environment rather than a regular
kernel printf.

Do our best to plug some memory leaks (VPD data, jumbo memory buffer,...).
Log if we cannot free because memory still in use[1].
Change locking to avoid ''acquiring duplicate lock of same
type: "network driver"'' and potential deadlock. Also seems to fix LOR #063.
[1] This change does not solve problems if buffers are still in use when
unloading if_sk.ko. There is ongoing work which will address jumbogram
allocations in a more general way.

doing that in bfe_stop().
This should fix a panic recently reported on -current occuring when taking
device down then up. In the original implementation, an "ifconfig bfe0 down"
triggers bfe_stop(), which also destroys all TX/RX descriptor dmamaps. Hence
the subsequent "ifconfig bfe0 up" would force the device to use those
already-released dmamap and thus panic the kernel.
