Monitor mode is able to TX by using injected frames. We should
not allow injected frames to be sent unless allowed by regulatory
rules. Since AP mode uses a monitor interfaces to transmit
management frames we have to take care to not break AP mode as
well while resolving this. We can deal with this by allowing compliant
APs solutions to inform mac80211 if their monitor interface is
intended to be used for an AP by setting a cfg80211 flag for the
monitor interface. hostapd, for example, currently does its own
checks to ensure AP mode is not used on channels which require radar
detection. Once such solutions are available it can can add this
flag for monitor interfaces.

Also call our own ieee80211_master_setup routine instead of
overwriting almost all the values from ether_setup; this
loses a few assignments that are pointless on the master

Giving the signal in dB isn't much more useful to userspace
than giving the signal in unspecified units. This removes
some radiotap information for zd1211 (the only driver using
this flag), but it helps a lot for getting cfg80211-based
scanning which won't support dB, and zd1211 being dB is a
little fishy anyway.

mac80211 notifies the RC algorithm if RTS/CTS and short preamble
are needed. The RC flags for MCS rates are currently not handled
by mac80211, and ath9k's RC doesn't set the flags either. Fix this.
Also, set the rts_cts_rate_idx inside the RC algorithm.

I hold back this patch for around a week to avoid
confusion. This is the second step of
"mac80211: Fixed BSSID handling revisited".
With it, in the situation of a strange merge to the
same BSSID (e.g. caused by a TSF overflow) only
reset_tsf() is called.
And sta_info_flush_delayed() is only called if you
change the network manually, not on an automatic
BSSID merge.

This fixes a bug when creating a new IBSS network with a
fixed BSSID. The fixed BSSID situation is now with one of
my last patches handled in ieee80211_sta_find_ibss()
function.
It's more robust to test against
(ifsta->flags & IEEE80211_STA_PREV_BSSID_SET), because
ifsta->state is not seted right in every situation and so
the creating of the new IBSS network sometimes hangs after
the first try to scan for a network to merge.

If we have new found information about our location and the
current country regulatory domain does not have passive scan
flag requirements we should be able to actively scan now on those
channels.
Since AP functionality is not allowed where passive scan flags are
set this means if you have a world regulatory domain and you get a
country IE that allows that channel (with active scan) then we lift
the passive-scan requirement so you can then use AP mode.

The iwl_rxon_cmd is really just a iwl3945_rxon_cmd structure extension.
So, we can use the *_rxon fields from iwl_priv instead of the 3945 specific
ones (*39_rxon). We have to then be careful when submitting REPLY_RXON host
commands, since the command length as to be set according to the HW. As
another precaution the reserved4 and reserved5 fields are cleared before being
sent to the 3945.
With the *39_rxon removal, a lot of duplicated code can be removed from the
3945 code base.

Several devices need to insert some "pre headers" in front of the
main packet data when they transmit a packet.
Currently we allocate only 16 bytes of pad room and this ends up not
being enough for some types of hardware (NIU, usb-net, s390 qeth,
etc.)
So increase this to 32.
Note that drivers still need to check in their transmit routine
whether enough headroom exists, and if not use skb_realloc_headroom().
Tunneling, IPSEC, and other encapsulation methods can cause the
padding area to be used up.
