atw seems to work better now that it gets this right: for one thing,
the RSSI can be seen to change as I walk around the office with my
laptop.
Thanks to Todd C. Miller for pointing out my mistake.
ieee80211_media_change handles a lot more conditions than
wi_media_change did.
This helps with the second bug mentioned in kern/25604, which causes
"SIOCSIFMEDIA: Invalid argument."
is anti-social -- especially given that there's no way to upgrade again short
of rebooting.
Also, downgrade UDMA modes more slowly. It's entirely possible that they're
using an 80-wire cable, but it's just too long for the higher modes, or there
is minor crosstalk.
registers are registers that overlap with others on many controllers, but
which may actually be distinct on some controllers. Right now, the two
shadows are:
- wd_status (usually overlaps wd_command)
- wd_features (usually overlaps wd_error)
Add a new helper function, wdc_init_shadow_regs(), used to initialize
the shadow register handles on controllers where they do actually overlap.

Some ATAPI device never get out of busy if touched too fast after a reset.
Delay value from atapi_wdc.c; fix problem reported by Nicolas Joly on
current-users.
real save data pointers when we get the message (or rather, at disconnect
time following the message).
Factor out code to do this, and to deal with xs->resid, in siop_common.c.
What we do here seems to trigger interrupts on some pcmcia adapters, which
cause the kernel to hang.
Add some WDCDEBUG_PRINT((), DEBUG_PROBE).
Avoid touching registers of nonexistent drives, once we know which drive is
or is not here.
This makes the "IBM PCMCIA Portable CD-ROM Drive" (external CD drive with
PCMCIA adapter) work.
Some controllers/drives (e.g. SataLink 3114 with WD Raptor) require
it. Should fix kern/23808 by Chris Gilbert, patch suplied by Chris Gilbert
on tech-kern, extended to all places enabling interrupts by me.

update copyright notice for 2004
----------------------------
add new statistics
Obtained from: madwifi
----------------------------
update radiotap support to reflect recent changes:
o move tx taps from ath_start to ath_tx_start so lots more
state is available to tap
o add tx flags
o add tx rate
o add tx power (constant for the moment)
o add tx antenna state
----------------------------
do proper subclassing of node free+copy; the previous hack falls apart when
the 802.11 layer does useful work
Obtained from: madwifi
----------------------------
transmit beacon frames directly instead of defering them to a swi; there
was too much delay
Obtained from: madwifi
----------------------------
update copyright notice for 2004
----------------------------
radiotap updates:
o force little-endian byte order for header
o pad header to 32-bit boundary to guard against applications that assume
packet data alignment

use correct malloc type to allocate struct ieee80211_node's

check more quickly (and directly) if an interrupt is pending; this reduces
work done in ath_intr when the irq is shared

cleanup descriptor allocation if attach fails

remove use IEEE80211_C_RCVMGT

Don't announce MAC addresses twice.
(ieee80211_ifattach() calls ether_ifattach().)
----------------------------
Make this compile on amd64.
"I'll cope" by: sam
----------------------------
When draining the tx queue reclaim any node references held in packets.
This fixes a problem when operating as an AP where clients would get
stuck in the node table because the reference count never went to zero.
----------------------------
When ath_hal_stoptxdma returns an error dma is still likely stopped
so don't just stop trying to send a beacon frame or we'll be more likely
to lose sync. This only seems to happen on some older chips.
----------------------------
use ath_reset instead of ath_init when recovering from a watchdog timeout:
resetting the hardware is sufficient, no need to reset the 802.11 fsm
----------------------------
make hw.ath.debug a tunable
----------------------------
make hw.ath.outdoor and hw.ath.countrycode tunables
----------------------------
split debugging messages up into classes;
ah_debug is now treated as a bit vector

state is available to tap
o add tx flags
o add tx rate

----------------------------
o eliminate widespread on-stack mbuf use for bpf by introducing
a new bpf_mtap2 routine that does the right thing for an mbuf
and a variable-length chunk of data that should be prepended.
o while we're sweeping the drivers, use u_int32_t uniformly when
when prepending the address family (several places were assuming
sizeof(int) was 4)
o return M_ASSERTVALID to BPF_MTAP* now that all stack-allocated
mbufs have been eliminated; this may better be moved to the bpf
routines
on x86 boxes. There must be a better way to deal with this that works
well for everyone. In the meantime, back out to the version that works
for more people.
