4fc1dda91d Make the fxp driver work on alpha, rather than panic the machine on boot
and/or when using the card.

o Convert the driver to using bus_space.  This allows alphas with
fxp's to boot, rather than panic'ing because rman_get_virtual()
doesn't really return a virtual address on alphas.

o Fix an alpha unaligned access error caused by some misfeature of
gcc/egcs: if link_addr & rbd_addr in the fxp_rfa struct are 32 bit
quantities, egcs will assume they are naturally aligned. So it will do
a ldl & some shifty/masky to twiddle 16 bit values in fxp_lwcopy().
However, if they are 16-bit aligned, the ldl will actually be done on
a 16-bit aligned value & we will panic with an unaligned access
error... Changing their definition to an array of chars seems to fix
this.  I obtained this from NetBSD.

I've tested this on both i386 & alpha.

dd68ef1623 Recognise the new 82559 chip id as used on the InBusiness 10/100 adapter.
I have an 82559 card with the same id as the other 8255[78] chips, but
that was made with a date code of 0699 (June 99).  The submitter shows
this working with the probe etc, but doesn't actually say it works as
on the ethernet. :-) Assuming it does, this is a RELENG_3 merge candidate.

a09bee1aa8 Fixed pedantic semantics errors (bitfields not of type int, signed int
or unsigned int (this doesn't change the struct layout, size or
alignment in any of the files changed in this commit, at least for
gcc on i386's.  Using bitfields of type u_char may affect size and
alignment but not packing)).

397f9dfe26 Work around a bug in the 82557 NIC where the receiver will lock up
if it is in 10Mbps mode and gets certain types of garbage prior to
the packet header. The work-around involves reprogramming the
multicast filter if nothing is received in some number of seconds
(currently set at 15). As a side effect, implemented complete support
for multicasting rather than the previous 'receive all multicasts'
hack, since we now have the ability to program the filter table.
Fixed a serious bug which crept in with the timeout() changes;
the cookie was only saved on the first timeout() call in fxp_init()
and wasn't updated in the most common place in fxp_stats_update()
when the timeout was rescheduled. This bug would have resulted in
an eventual panic if fxp_stop() was called (which happens when any
interface flags are changed, for example).
Fixed a bug in Alpha support that would have caused the TxCB
descriptor chain to span a page boundry, causing serious problems
if the pages didn't happen to be contiguous.
Removed some gratuitous bit masking that was left over from an
older implementation.
Fixed a bug where too much was copied from the configuration
template, spilling over into memory that followed it.
Fixed handling of if_timer...it was cleared too early in some cases.

854d14213e Added support for the Intel 82555 PHY chip which is being used on newer
Pro/100B cards. Full duplex should work now, although it hasn't been
tested.

6ebc315326 Added support for newer cards that have the DP83840A PHY chip.
Fixed a bug in fxp_mdi_write - a hex number was missing a preceding 0x
and this was causing the routine to not wait for a PHY write to complete.
Added support for link0, link1, and link2 flags to toggle auto-
negotiation, 10/100, and half/full duplex:

link0	disable auto-negotiation

	When set, these flags then have meaning:

	-link1	10Mbps
	link1	100Mbps
	-link2	half duplex
	link2	full duplex

...needs a manual page.

dccee1a193 Fixed two deficiencies in the driver that have existed since it was
written:

1) Full duplex mode is now supported (and works!)
2) The 10Mbps-only PCI Pro/10 should now work (untested, however)

Thanks to Justin Gibbs for providing a PCI bus analyzer trace while the
Intel Windows driver was configuring the board...this made it possible
to figure out the mystery bit that I wasn't setting in the PHY for full
duplex to work.

33d14d8671 Do "selective" reset rather than full reset...the manual specifically
says not to do the full reset because it can lock up the PCI bus if the
chip is active. Added various PORT command definitions to facilitate
this.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

23a0ed7c08 Increased the number of Tx segments from 13 to 29 to reduce the need to
recopy to near zero. Wrote the necessary code to recopy the mbuf chain
into another buffer if there are too many mbufs in the chain.
