when sharing an interrupt with other devices:
check sc->sc_enabled, and drop the interrupt if its' off.
Also check for IFF_RUNNING, on advice of Enami Tsugotomo.
instead of addr1 and addr2. THis means that tcpdump -e will show the
correct MAC address for communications with access points instead of showing
the BSSID.
In the future there should be 802.11 support for bpf/libpcap/tcpdump,
but that is aways down the road.
Also fix a typo in a comment.
u_int8_t array to struct ieee80211_nwid to prepend length field.
The length field is necessary because IEEE 802.11 spec doesn't prohibit
even '\0' for SSID.
Though the name and the value of SIOC... macro is unchanged, this change
breaks binary compatibility. The only affected userland program on the
tree is ifconfig(8).
As Jason suggested on tech-net, it is better than live with problems
since there are no releases for this ioctls yet.
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.
ETHERTYPE_IPV6 packets are encapsulated by RFC1042 encap.
Tested with Japanese card, with WaveLan bridge (wiconfig -p 1).
NOTE: I dunno if encapsulating IPv6 packets by RFC1042 is the correct way,
as RFC1042 only defines behavior for ETHERTYPE_{IP,ARP,REVARP} packets.
Since WaveLan bridge encapsulates IPv6 packets with RFC1042, we have no
choice.
Gather joined multicast addresses via SIOCADDMULTI, and configure multicast
filter properly. This is also required for IPv6 support
(which heavily depends on multicast).
Fix IFF_RUNNING management
- to prevent IFF_RUNNING from raised on "wiconfig", before "ifconfig up"
- to prevent the driver from occupying extra interrupts on "ifconfig up",
then "down", then "up".
