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.
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 :-(
This commit move struct arpcom from <netinet/if_ether.h> to

support for this driver, producing the dreaded "device allocation

two compiler warnings. The compilation still "succeeded" anyway.
use a Linker Set. Note, if a driver is loaded as an LKM if will have
to use the function call, but since none of the existing drivers
are loadable, this made things cleaner and boot messages nicer.

* Kill individual drivers 'suspend' routines, since there's no simple/safe
way to suspend/resume a card w/out going through the complete probe
at initialization time.
* Default to using the apm_pccard_resume sysctl code, which basically
pretends the card was removed, and then re-inserted. Suspend/resume
is now 'emulated' with a fake insert/removal. (Hence we no longer
need the driver-specific suspend routines.)

* Rename/reorder all of the pccard structures, change many of the member
names to be descriptive, and follow more closely other 'bus' drivers
naming schemes.
* Rename a bunch of parameter and local variable names to be more
consistant in the code.
* Renamed the PCCARD 'crd' device to be the 'card' device
* KNF and make the code consistant where it was obvious.
* ifdef'd out some unused code
shown to be harmful in that it results in the card not being detected
properly on warmboot due to the station address failing to be read
correctly from the NVRAM.
delay that without this the performance is unacceptable. The 83C690,
83C790, and 83C795 chips which this affects are all designed to work
with 0 waitstates in 16bit mode.
Also cleaned up the toggling of 16bit access mode that occurs during
normal operation; the previous code may not have done the right thing
in all cases.
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.

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().
function ed_attach_NE2000_pci() in if_ed.c passes
an uninitialized block of memory (got with malloc())
to ed_attach. This prevents a proper initialization
of the device descriptor and in my case causes a panic
during the probe, while printing out device info.

too much about the icu (most only use it to convert `n' to `IRQn'). isa.h
is only used by ioconf.c and by a few drivers that know too much about

The first PCI card will get a unit number one higher than the highest
defined for any ISA card of the ED type, e.g. if ed0 and ed1 are
configured, then the PCI cards will be ed2, ed3, ...
BEWARE: If you have configured your kernel as ed0 with the port address
as assigned by the PCI BIOS, then your card will be found by both the
PCI and ISA probes, and bad things may happen. Make sure to restore
the original port address form the GENERIC kernel for the ed0 device!

- 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
Fixed two cases of "=" that should have been "==" in card type comparison.
Simplified expression that checks for interface up/down.
Moved ed_ring_copy to before its first use so that it's inlined as intended.
Change mbuf allocation policy so that a received packet is stored in just
an mbuf header (no cluster) if it will fit in one.
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!).
misplaced extern declarations (mostly prototypes of interrupt handlers)
that this exposed. The prototypes should be moved back to the driver
sources when the functions are staticalized.
Added idempotency guards to <machine/conf.h>. "ioconf.h" can't be
included when building LKMs so define a wart in bsd.kmod.mk to help
guard against including it.
Remove confusing backwards compatibility code that allowed driver to be
used in pre-4.4 releases. The 3COM card's use -link2 to switch tranceivers.

it is not guaranteed to work 100% correctly at this time
but as we had several people trying to work on it
I figured it would be better to get it checked in so
they could all get teh same thing to work on..

but on 2.0
more changes and stuff will be merged in from other developers now that this is in.

scheduled for demolition. This is a first step: get rid of if_zereg.h,
by adding the five extra definitions to if_edreg.h.
Also add some definitions which will become needed when if_ze.c gets
replaced entirely by pccard and if_ed.c. (this is a 2.1.0 candidate)
the 802.3 frames generated by the DC21040 (which does automatic padding
of less-than-minimum frames) and the frames generated by the 'ed'
driver, I've found that there is indeed a bug in the size of "ETHER_MIN_LEN"
as reported by several people, John Hay being the most recent. The driver
was actually setting the length to 6+6+2+50 (64 bytes), which when adding
in the CRC (which is automatically appended to the frame and not included
in the length), the minimum frame is 4 bytes larger than it is supposed to
be. All of this is confirmed by tcpdump showing 50 bytes of data for
minimum frames from the 'ed' cards and 46 bytes from 'de' cards. This
analysis has also revealed that there is garbage in the un-filled in
portion at the end of the minimum frames from the 'ed' driver; I don't
plan to fix this.
For those where it was easy, drivers were also fixed to call
dev_attach() during probe rather than attach (in keeping with the
new design articulated in a mail message five months ago). For
a few that were really easy, correct state tracking was added as well.
The `fd' driver was fixed to correctly fill in the description.
The CPU identify code was fixed to attach a `cpu' device. The code
was also massively reordered to fill in cpu_model with somethingremotely
resembling what identifycpu() prints out. A few bytes saved by using
%b to format the features list rather than lots of ifs.
properly from the beginning:
1) The `kern_devconf' struct should be a part of the driver's
`softc' structure (now it is).
2) The `description' should say what the device actually is,
rather than just giving a model number (now it does).
3) The device should be registered even if the probe fails, so
that it can be reconfigured later.
4) For netifs, the device state should follow the IFF_UP flag.
Other network interfaces should follow this example. (Please?) Eventually
there should be a rundown routine doing the equivalent of setting IFF_UP
off, and perhaps more if warranted.
- /sys/i386/isa/if_ed.c doesn't quite know how to deal with SMC EtherEZ
ethernet cards. The EtherEZ looks just like the Elite Ultra, except it
has only 8K of shared memory. The only way to have it properly detected
is to zero and test a few bytes of memory just about the first 8K region.
If it clears properly, it's an Elite Ultra, otherwise it's an EtherEZ.
I've also got an EtherEZ patch for netboot (Makefile, ether.c and ether.h).
- /sys/i386/isa/syscons.c wraps at the next to the last column rather than
the last column, like it should. You don't really notice this unless you
use certain programs that write all the way out to, say, the 80th column,
like VMSmail. Along with a one-line fix for this are some changes to
implement a non-blinking cursor. Put 'options "NOBLINK_CURSOR"' in your
config file and give it a try. :)
