for transmit to the adapter, not when we receive a transmit interrupt
indicating that they were sent. This fix now allows tcpdump to produce
sane results by recording the timestamp at the point where the mbuf was
actually transmitted.
the case where we receive a packet that wraps from the end of the
RX buffer back to the start. This fixes an unaligned access trap on
the alpha with NFS.
<sys/bio.h>.
<sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall
not be made a nested include according to bdes teachings on the
subject of nested includes.
Diskdrivers and similar stuff below specfs::strategy() should no
longer need to include <sys/buf.> unless they need caching of data.
Still a few bogus uses of struct buf to track down.

not u_long. On i386's with 64-bit longs, returning u_longs indirectly
in (more than) the space reserved for uintptr_t's tended to corrupt the
previous frame pointer in the stack frame, so it was not easy to debug.
The type mismatches are hidden by the bogus cast in DEVMETHOD().
Note that if_aue doesn't strictly depend on usb because it uses the
method interface for calls rather than using internal symbols, and
because it's a child driver of usb and therefore will not try and do
anything unless the parent usb code is loaded at some point. if_aue does
strictly depend on miibus as it will fail to link if it is missing.
- Break out the support for the XMAC II's PHY into an miibus driver.
- Reorganize the probe/attach stuff using newbus. Each XMAC is now
attached to the parent GEnesis controller using newbus. This is
necessary since each XMAC must also have an attached miibus, and
the miibus read/write register routines need to be able to get
at the softc struct for each XMAC, not the one for the parent
controller. This allows me to get rid of the grotty code I added
for selecting the unit numbers for the ifnet interfaces: the unit
numbers are now derived from the newbus-assigned unit numbers,
which should track with the ifnet interface numbers. I think.
At the very least, there should never be any collisions.
- Add support for the SK-9821 and SK-9822 1000baseTX adapters. Special
thanks to SysKonnect for loaning me two adapters for testing.
non-device code.
* Re-implement the method dispatch to improve efficiency. The new system
takes about 40ns for a method dispatch on a 300Mhz PII which is only
10ns slower than a direct function call on the same hardware.
This changes the new-bus ABI slightly so make sure you re-compile any
driver modules which you use.
This don't hurt anything.

address size that is different than the standard 6bits. This fixes
support for the Compaq NC3121 card, certain newer Intel Pro/100+
cards, and should also fix integrated NICs on SuperMicro and Compaq
motherboards.
The auto-sizing algorithm was taken from NetBSD (thanks!), which I
think got it from Linux originally.
Thanks also to Andrew Sparrow <spadger@best.com> and Joe Moore
<jomor@ahpcns.com> for supplying me with unworking Compaq and Intel
cards to develop and test the fixes with.
cardbus bridge init routine for all cardbuses. This routine attempts
to compensate for BIOSes that do not setup the cardbus bridge into
legacy mode. Since this is becoming more common, and cardbus pci
cards have appeared on the market, this makes sense.
Do some TI113x specific initialization. This came in as part of the
patch. Report TI1[1234]XX specific config registers protected by
bootverbose.
Minor code cleanup while I'm here. I've also removed the unused code
present in the original patches, and cleaned it up slightly in places
as well.
The original patches supported more than one card, but these patches
support just one. We should likely revisit this in the future.
This makes the Compaq card that Walnut Creek CD purchased for me work
in my bouncer box.
This is a MFC candidate. However, I'd like to get some airtime on
these patches on as many laptops as possible before doing the MFC. It
does change things somewhat. In theory, apart from the minor TI
tweaks, this shouldn't change anything if the bridge is in legacy mode
already.

Make the public interface more systematically named.
Remove the alternate method, it doesn't do any good, only ruins performance.
Add counters to profile the usage of the 8 access functions.
Apply the beer-ware to my code.
The weird +/- counts are caused by two repocopies behind the scenes:
kern/kern_clock.c -> kern/kern_tc.c
sys/time.h -> sys/timetc.h
(thanks peter!)
it's options COMPAT_OLDISA and COMPAT_OLDPCI. This is meant to be a
fairly strong incentive to update the older drivers to newbus, but doesn't
(quite) leave anybody hanging with no hardware support. I was talking with
a few folks and I was encouraged to simply break or disable the shims but
that was a bit too drastic for my liking.
platform we're running on so we know how many bits to reserve at the top
end for the 'hose' value. It turns out that there's *just* enough room
to support all possible hoses on TurboLaser.
