1ed9e51a4d Fix sf_probe() to detect the card type properly. I botched the reading
of the subsystem ID when I converted to newbus. The driver still detects
the chipset and still works but fails to identify the exact card.

518dee7dbb Add a pointer to "controller miibus0" for people who will not read the
commit messages or GENERIC and insist on running -CURRENT.
It probably won't work, but it's worth a try.

ba2cb70286 #ifdef out the definition for the small packet RX ring. I ended up only
using one RX ring because of the alignment issue, so we may as well save
a few K of memory by not allocating space for it.

3de9d6fbe4 Don't restrict our requests for contiguous memory to addresses >= 1MB.
This fixes, at least, panics in ncr_attach() on i386's with about 5MB
of memory.  The restriction was a hack to leave some low memory for ISA
DMA, but on i386's we now allocate pages from the top down, so all the
restriction did was cause our allocations to fail when there is no free
memory above 1MB.

c9ce464cb7 Remember to clear the IFF_RUNNING and IFF_OACTIVE flags in sf_stop() and
sk_stop().

691c152864 This commit adds device driver support for Adaptec Duralink PCI fast
ethernet controllers based on the AIC-6915 "Starfire" controller chip.
There are single port, dual port and quad port cards, plus one 100baseFX
card. All are 64-bit PCI devices, except one single port model.

The Starfire would be a very nice chip were it not for the fact that
receive buffers have to be longword aligned. This requires buffer
copying in order to achieve proper payload alignment on the alpha.
Payload alignment is enforced on both the alpha and x86 platforms.
The Starfire has several different DMA descriptor formats and transfer
mechanisms. This driver uses frame descriptors for transmission which
can address up to 14 packet fragments, and a single fragment descriptor
for receive. It also uses the producer/consumer model and completion
queues for both transmit and receive. The transmit ring has 128
descriptors and the receive ring has 256.

This driver supports both FreeBSD/i386 and FreeBSD/alpha, and uses newbus
so that it can be compiled as a loadable kernel module. Support for BPF
and hardware multicast filtering is included.
