6182fdbda8 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

35f069d08b pci_device pd_probe function changed from returning char * to returning
const char *.  Originally I was going to add casts from const char * to
    char * in some of the pci device drivers, but the reality is that the
    pci device probes return constant quoted strings.

91aa9f9055 Clear out transmit descriptor memory in fxp_attach when it's malloced.
fxp_stop is called as the first thing in fxp_init, and if the tx desc
list has junk in it, the system may panic. This bug showed up as a side
effect of the changes in rev 1.56, but has been in the code since the
beginning.

David Greenman
3114fdb4c0 Implemented a more sophisticated mechanism for handling transmitter
interrupts which now defers them until the transmit queue if filled
up with completed buffers. This has two advantages: first, it reduces
the number of transmitter interrupts to just 1/120th of the rate
that they occured previously, and two, running down many buffers
at once has much improved cache effects.

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)).

ecbb00a262 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

1d5e9e2255 Make INET a proper option.
This will not make any of object files that LINT create change; there
might be differences with INET disabled, but hardly anything compiled
before without INET anyway.  Now the 'obvious' things will give a
proper error if compiled without inet - ipx_ip, ipfw, tcp_debug.  The
only thing that _should_ work (but can't be made to compile reasonably
easily) is sppp :-(

<net/if_arp.h>.

6f5818b074 Two changes which should make the system less suseptible to receiver
overruns (not that it was a problem, but it could be):

1) Doubled the number of receive buffers in the DMA chain to 64.
2) Do packet receive processing before transmit in the interrupt routine.

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.

0633918017 Check that the received packet length indicated by the card is at least
large enough to contain the ethernet header. There appears to be a

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.
