6318197e68 Made a couple of minor optimizations that improve performance of the
common case of the interrupt routine by about 20%.

51a534883a Don't include <sys/ioctl.h> in the kernel. Stage 2: include
<sys/sockio.h> instead of <sys/ioctl.h> in network files.

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.

6875d25465 Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

001696da5b Changed several configuration options:
Disabled the DMA byte counters - I had it this way originally and this is
the recommended setting.
Set crscdt to CRS only (0) since this is what it should be for an MII PHY.
Also fixed some comments.

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.

6e39e59963 Don't include the short-frames counter in with the input errors. This
counter is incremented on all short frames, including those that are
the result of collisions.

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.

477180fbc8 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).

fb5831565c 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().

4458ac71b1 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>.

78fb85bbf7 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.

1cd443ace8 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.

eadd5e3a24 Fixed a bug in the receive buffer allocation code that resulted in a
panic if an mbuf cluster couldn't be allocated. This was caused by a
failure to re-initialize m_data when the old mbuf/mbcluster was recycled.

4a684684f4 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).

9b44ff2214 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

ae12cdda30 This driver really is for the Pro/100B and not for the Pro/100 (and in fact
doesn't even work with a Pro/100)...updated to reflect this.

4a5f1499b0 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!).
