- Setup PHY before handing control to NVidia API setting
speed, duplex, enabling interrupts, etc.
- Add restriction of MAXADDR_32BIT for high address to contigmalloc
to make the driver work on machines with 4+GB of memory.

- Implement cv_wait_unlock() method which has semantics compatible
with the sv_wait() method in IRIX. For cv_wait_unlock(), the lock
must be held before entering the function, but is not held when the
function is exited.
- Implement the existing cv_wait() function in terms of cv_wait_unlock().

being hold by current thread or ignored by current process,
otherwise, it is very possible the thread will enter an infinite loop
and lead to an administrator's nightmare.

Add 'reset' subcommand for resetting statistics.
transmitted bits was between 8.6180us and 8.6200us when we used a RCLK
of 16.500MHz. This is a little low (should be 8.6805us). This error
is exactly the error one would expect if it actually had a 16.384MHz
watch oscillator (as suggested by garrett) instead of using the PCI
RCLK. Assume that the pci clock therefore wasn't really used, but
instead the cheap 16.384MH watch quartz oscillator. This gives bits
in the 8.6800us to 8.6810us ranage, which matches theoretical.

- Move PUSH_FRAME and POP_FRAME to asmacros.h and use PUSH_FRAME in
atpic entry points.
- Move PCPU_* asm macros out of the middle of the asm profiling macros.
- Pass IRQ vector argument as an int rather than void * to reduce diffs
with i386.
- EOI the lapic in C for the lapic timer handler.
- GC unused Xcpuast function.
- Split IPI_STOP handling code of ipi_nmi_handler() out into a
cpustop_handler() function and call it from Xcpustop rather than
duplicating all the logic in assembly.
- Fixup the list of symbols with interrupt frames in ddb traces.
Xatpic_fastintr* have never existed on amd64, and the lapic timer
handler and various IPI handlers were missing.
- Use trapframe instead of intrframe for interrupt entry points (on amd64
the interrupt vector was already a separate argument, so the two frames
were already identical) and GC intrframe.

cluster allocator, that wasn't MPSAFE. Instead, utilize our new generic
UMA jumbo cluster allocator. Since UMA gives us a 9k piece that is contigous
in virtual memory, but isn't contigous in physical memory we need to handle
a few segments. To deal with this we utilize Tigon chip feature - extended
RX descriptors, that can handle up to four DMA segments for one frame.
Details:
o Remove bge_alloc_jumbo_mem(), bge_free_jumbo_mem(),
bge_jalloc(), bge_jfree() functions.
o Remove SLIST heads, bge_jumbo_tag, bge_jumbo_map from softc.
o Use extended RX BDs for Jumbo receive producer ring, and
initialize it appropriately.
o New bge_newbuf_jumbo():
- Allocate an mbuf with Jumbo cluster with help of m_cljget().
- Load the cluster for DMA with help of bus_dmamap_load_mbuf_sg().
- Assert that we got 3 segments in the DMA mapping.
- Fill in these 3 segments into the extended RX descriptor.
