are at the end of the node queue. Change the reference-counting
discipline: ni->ni_refcnt indicates how many times net80211 has
granted ni to the driver. Every node in the table with ni_refcnt=0
is eligible to be garbage-collected. The mere presence of a node
in the table does not any longer indicate its auth/assoc state;
nodes have a ni_state variable, now. A sysctl,
net.link.ieee80211.maxnodecache, controls the maximum LRU cache
size.
While I am here, patch ieee80211_find_node_for_beacon to do a "best
match" by bssid/ssid/channel, not a "perfect match." This keeps
net80211 from caching duplicate nodes in the table.
Fix promiscuous mode, taken from FreeBSD.
Fix to re-enable the card after suspend/resume.
Reflect current operational rate to if_media interface.
Avoid duplicate copy in transmit.
Move most of debug printfs into IFF_DEBUG.
Disable ANCACHE - designed for IPv4 only and no one use it.
Add IFF_ALLMULTI flags, as we don't have multicast filter.
Convert bzero/bcopy to memset/memcpy.
... sorry for jumbo commit.
Handle special case for IFF_PROMISC. If only IFF_PROMISC
flag is changed, do not call an_init() to avoid initiating
reassociation to another access point. It is really
helpful for tcpdump(8).

- ack command after clearing busy bit

probably due to heavy load of firmware in receiving.
timeouts).
stop driver after suspend.

(RID 0xff50 or 0xff68 access failed)
Though ifconfig -m no longer show 5Mbps/11Mbps for PC4500 by this fix,
I cannot find how to set fixed transmit speed to the firmware.
FreeBSD version of driver apparently ignore the value set by ancontrol(8).
This is very adhoc work for IETF meeting.
- Since it seems that 'an' and 'wi' have similar hardware, low level
functions should be shared.
- There are PCI/ISA cards of Aironet but not supported yet.
- The wiconfig interface is changed so that wiconfig cannot be used.
- 'ancontrol' of FreeBSD is not ported.
- Only infrastructure mode is tested.
- WEP is not supported.
Though I only have an Aironet card, Cisco card should be expected to work.
