When dispatching frames saved on the power save queue to a
station exiting power save mode prepend them to the driver's
send q instead of appending them. This insures the packets
are not misordered wrt any packets already q'd for the station.
This corrects a problem noticed when using a VoIP phone talking
to an ath card in ap mode; the misordered packets caused noise.

o change rssi to be signed in ieee80211_nodestats
o add noise floor in ieee80211_nodestats (use an implicit hole to
preserve layout); return it as zero until we can update the api's
so the driver can provide noise floor data
o add a bandaid so IEEE80211_IOC_STA_STATS works for sta mode; when
all nodes are in the station table this will no longer be needed
o fix braino in IEEE80211_IOC_STA_INFO implementation; was supposed
to take a mac address and return info for that sta or all stations
if ff:ff:ff:ff:ff was supplied--but somehow this didn't get implemented;
implement the intended semantics and leave a compat shim at the old
ioctl number for the previous api
Note this changes the api for IEEE80211_IOC_STA_INFO but old binaries
will continue to work. FreeBSD_version bumped so apps can track the
change (no such applications are known to exist but just in case).
Move conditional preprocessing out from the IEEE80211_DPRINTF macro
invocation. Per C99 6.10.3 paragraph 11 preprocessing directives
appearing as macro arguments yield undefined behavior.
Ensure outbound data packets in hostap mode are delivered only
to stations that are associated by making ieee80211_find_txnode
return NULL when a unicast frame is to be delivered to an
unassociated station.
enable "aggressive mode" only when operating in ap or station mode; in
particular this fixes use of wme in adhoc demo mode, it wasn't possible
to set the txop limit because the aggressive mode logic would override
- Use VLAN_TAG_VALUE() not only to read a dot1q tag
value from an m_tag, but also to set it. This reduces
complex code duplication and improves its readability.
- Fix VLAN_INPUT_TAG() macro, so that it doesn't touch mtag in
case if memory allocation failed.
- Remove fourth argument from VLAN_INPUT_TAG(), that was used
incorrectly in almost all drivers. Indicate failure with
mbuf value of NULL.
