d1cdbc3c81 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.

179a5ad365 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.

f0711d970f 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.

f096e34225 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
condition where the card can return "0" in some failure cases, and this
causes bad things to happen (a panic).

5bea6a2fcd 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.

8032f5328d 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.

635a58929b Changed several configuration options:
Disabled the DMA byte counters - I had it this way originally and this is
the recommended setting.

57ba1e0511 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.

808a36ef65 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.

19e2ac904f Use the new if_multiaddrs list for multicast addresses rather than the
previous hackery involving struct in_ifaddr and arpcom.  Get rid of the
abominable multi_kludge.  Update all network interfaces to use the
new machanism.  Distressingly few Ethernet drivers program the multicast
filter properly (assuming the hardware has one, which it usually does).

1665979d2e 1) Implement SIOCSIFMTU in ether_ioctl(), and change ether_ioctl's return
type to be int so that errors can be returned.
2) Use the new SIOCSIFMTU ether_ioctl support in the few drivers that are
   using ether_ioctl().
3) In if_fxp.c: treat if_bpf as a token, not as a pointer. Don't bother
   testing for FXP_NTXSEG being reached in fxp_start()...just check for
   non-NULL 'm'. Change fxp_ioctl() to use ether_ioctl().

8c49d9975c Removed nested include if <sys/socket.h> from <net/if.h> and
<net/if_arp.h> and fixed the things that depended on it.  The nested
include just allowed unportable programs to compile and made my
simple #include checking program report that networking code doesn't
need to include <sys/socket.h>.

fbb6d9b119 Backed out one of my "performance optimizations" as it results in sometimes
not resuming the NIC as required for transmit. Thanks to Alan Cox
<alc@cs.rice.edu> for noticing this.
Added another performance optimization to compensate. :-)

Changed crscdt to 1...strange, but this seems to be needed for some reason
despite what the manual says.

e461bbf70b Fixed a bug with the management of the pointer to the first TxCB in the
ring that caused wrong things to happen sometimes.
Doubled the number of transmit descriptors to 128 so that the internal
FIFO in the NIC can be fully filled when dealing with small packets.
Several minor performance improvements.

6065d244a1 When the devconf stuff was ripped out of the kernel, the ripper neglected
to deal with the fact that we relied on devconf to do the shutdown
callouts in various drivers. The changes in this commit are to add support
for device shutdown in this driver via the new at_shutdown() mechanism.
Similar changes need to be made to all of the other drivers that need
a shutdown routine called (if_de.c comes to mind immediately).

25ee6cca2a Clean up Ethernet drivers:
- fill in and use ifp->if_softc
	- use if_bpf rather than private cookie variables
	- change bpf interface to take advantage of this
	- call ether_ifattach() directly from Ethernet drivers
	- delete kludge in if_attach() that did this indirectly

8156a5707a all:
Removed ifnet.if_init and ifnet.if_reset as they are generally unused.
Change the parameter passed to if_watchdog to be a ifnet * rather than
a unit number. All of this is an attempt to move toward not needing an
array of softc pointers (which is usually static in size) to point to
the driver softc.

if_ed.c:
Changed some of the argument passing to some functions to make a little
more sense.

if_ep.c, if_vx.c:
Killed completely bogus use of if_timer. It was being set in such a way
that the interface was being reset once per second (blech!).
