is read one clock edge too late. This bit is driven low by
slave (as any other input data bits from slave) when the clock
is LOW. The current code did read the bit after the clock was
driven high again.

up the stack intact (required significant changes to some drivers)

The former consolidates the operations of if_attach(), ng_ether_attach(),
and bpfattach(). The latter consolidates the corresponding detach operations.

Also, remove the (incomplete) hack for matching ethernet headers
in the ip_fw code.
The good news: net result of 1016 lines removed, and this should make
bridging now work with *all* Ethernet drivers.
The bad news: it's nearly impossible to test every driver, especially
for bridging, and I was unable to get much testing help on the mailing
lists.

that seems to be working (I have a MF card that has a 336 modem and
ethernet that the probe routine finds, but the attach fails on because
pccardd doesn't do what you'd like with MF cards all the time).
o Modify xe driver to use this.
There's still some issues with this code, so xe can't map the cis just
yet. I'm thinking about how to resolve the issue. pccard_nbk's
pccard_alloc_resource is getting in the way.
Driver is not functional yet, but does compile. Tests with xe cards
indicates that it doesn't panic the machine when they are present, but
fail to probe. Interface help in the pcic/pccard layers are needed to
complete this driver.
This means that we will not have to have a bpf and a non-bpf version
of our driver modules.
This does not open any security hole, because the bpf core isn't loadable
The drivers left unchanged are the "cross platform" drivers where the respective
maintainers are urged to DTRT, whatever that may be.
Add a couple of missing FreeBSD tags.
* Conformance with Dingo specification. This includes:
Collision/error statistics gathering.
Multicast address filtering, eg. the hash filter.
Initialisation and interrupt handling sequences.
Note that I've started on some of this already in v1.20.
* The probe routine needs some more work, to identify oddities such as the
REM10.
* There are still problems with the autonegotiation code; specifically, it
won't autonegotiate with some 10/100 hubs. This might simply be the hardware
not getting along, in which case there's nothing we can do, but it's still
worth investigating
* CEM28/CEM33 support. Should be able to integrate this directly from the
Linux code.
* Performance enhancements:
Full-duplex on 10Mbit networks.
Virtual shared-memory mode.
Early send and receive modes.

The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it. cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.
cdevsw_add() will print an message if the d_maj field looks bogus.
Remove nblkdev and nchrdev variables. Most places they were used
bogusly. Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.
Move bdevsw() and devsw() functions to kern/kern_conf.c
Bump __FreeBSD_version to 400006
This commit removes:
72 bogus makedev() calls
26 bogus SYSINIT functions
if_xe.c bogusly accessed cdevsw[], author/maintainer please fix.
I4b and vinum not changed. Patches emailed to authors. LINT
probably broken until they catch up.
v1.19 (1999/04/15) updates the CEM56/REM56 support.
Current bugs & misfeatures
--------------------------
* CE2 cards still not working reliably. Unclear if this is related to
packet I/O code or interrupt handling.
* Autonegotiation support remains flaky. We're now OK with 10Mbit auto
hubs, but certain combination of hardware will fail to connect.

v1.18 (1999/04/08) adds support for CEM56 and REM56 multifunction cards.

v1.17 (1999/03/28) has xperimental fixes to 10Mbit autonegotiation and
CE2 input lockup.
KNOWN BUGS
==========
* Media auto-negotiation is definitely not right. It will work in most
circumstances and seems to connect OK to most 100Mbit networks, however some
pathological combinations of hubs/networks/peers seem to confuse it.
* CE2 support is somewhat flakey (ranging from 'works perfectly' to 'hangs the
machine' so far). I've fixed the probe routine and a potential lockup in
the output routine, but a lot of people still report that they can't receive
or transmit.
* You won't be able to use the modem and Ethenet parts of a multifunction card
simultaneously. This is limitation the current FreeBSD PCMCIA support.
Likewise, there is no support for CardBus devices.
