The __UNCONST macro is now used only where necessary and the RW macros
are gone. Most of the changes here are consumers of the
sysctl_createv(9) interface that now takes a pair of const pointers
which used not to be.
"oversize frame." Also, some an(4) instances (esp. w/ firmware
version 5+) would not reliably interoperate with some Cisco APs.
Add a sysctl for enabling/disabling debugging.
The problem with Aironet AP interoperability was that the rx frame
'gap' will sometimes be loaded with the 802.2 SNAP header, and
sometimes omitted, when connected to a Cisco AP; an(4) was *always*
discarding the gap. The problem with "oversize frames" was an
off-by-2 error in the frame-length arithmetic.
While we're here, pad some RIDs to the length that new firmware
really expects.
Thanks to Jim Miller for his valuable bug reports and testing, and
to Dheeraj Reddy for RID-length patches. Some clues from various
Linux drivers for Cisco/Aironet cards led to the gap fix.
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).
- strip unnecessary loop to get command result status
- ack command after clearing busy bit
XXX: it still sometimes get timeout to get status(0xff50) or statistics(0xff68)
probably due to heavy load of firmware in receiving.
timeouts).
stop driver after suspend.
XXX: should use command interrupt but no document...
XXX: status update sometimes failed perhaps due to collision.
(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.
