We need to fix wpa_supplicant because it checks whether the card has
ic_cryptocaps set. Since net80211 can do software encryption this check in
wpa_supplicant is wrong.
Realtek RTL8188CU/RTL8192CU USB IEEE 802.11b/g/n wireless cards.
This driver requires microcode which is available in FreeBSD ports:
net/urtwn-firmware-kmod.
Hiren ported the urtwn(4) man page from OpenBSD and Glen just commited a port
for the firmware.
TODO:
- 802.11n support
- Stability fixes - the driver can sustain lots of traffic but has trouble
coping with simultaneous iperf sessions.
- fix debugging

freed memory cannot be used during detach.
- Remove all panic() calls from the urtw driver because
panic() is not appropriate here.
- Remove redundant checks for device detached in
device detach callbacks.
- Use DEVMETHOD_END to mark end of device methods.

The following assumptions have been made:
umass - buffers passed from CAM/SCSI layer are OK
network - mbufs are OK.

- Make it easier to port the USB code to other platforms by only using
one set of memory functions for clearing and copying memory. None of
the memory copies are overlapping. This means using bcopy() is not
required.
- Fix a compile warning when USB_HAVE_BUSDMA=0
- Add missing semicolon in avr32dci.
- Update some comments.

The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.

I looked further into the magic 88-byte threshold after which the bug
occurs. It turns out that figure included the 24-byte tx_desc, and up
to 64 bytes of beacon frame (header+data).
rum_write_multi doesn't seem happy with writing >64 bytes at a time to
the MAC register. If I break it up into separate calls (e.g. bytes
0-63, then bytes 64-65, written at the appropriate offset) I see the
proper beacon frames being transmitted now.

It appears that the addition to uath(4) came in through PR kern/135009,
which had tested another device, the SMCWUSBTG2, successfully with uath(4)
and included the SMCWUSBG as it "has the same chipset". I can find no
other evidence that these two do actually share the same chipset. Moreover,
Linux treats the SMCWUSBG as a zyd(4) device also.
This reverts r223537.

While updating Tx stats, already freed node could be referred and cause
page fault. To avoid such panic, spool Tx stats in driver's softc. Then,
on every ratectl interval, grab node though ieee80211_iterate_nodes() and
update ratectl stats.

* Fix typo
* Use memset instead of bzero (hselasky @)

Drivers which rely on net80211 to create the beacon need to call
ieee80211_beacon_update() on iv_update_beacon() calls. This is required
that certain bits, e.g. TIM, get updated. A call to ieee80211_beacon_alloc()
is not enough because it does not care about flags which can only change
during runtime. By design a beacon is supposed to be allocated only once
while moving into RUN state.
To handle all possible calls to iv_update_beacon() the run_updateslot()
function has been revived and run_updateprot() has been added.
run_updateslot() handles slot time changes and run_updateprot() changes
to protection, both can change while nodes associate/leave.
