rather than a cpu-endian value.

Harvey Harrison b73d70ad86 mac80211: rx.c/tx.c remove more users of tx/rx_data->fc
Those functions that still use ieee80211_get_hdrlen are moved over
to use the little endian frame control.

Harvey Harrison 62bf1d762e mac80211: explicitly check skb->len
ieee80211_get_hdrlen_from_skb internally checks the skb is long enough to
hold the full ieee80211_hdr, else it returns zero.  Use ieee80211_hdrlen
which always returns the hdrlen and check the remaining room in the
skb explicitly when removing encryption headers or the qos control field.

Bruno Randolf 9deb1ae572 mac80211: radiotap: assume modulation from rates
use the rates ERP flag to derive CCK or OFDM modulation for the radiotap
header.

(it might be more correct to get this information from the hardware itself, but it
seems safe to assume this in most practical cases.)

Luis Carlos Cobo 8dbc1722a7 mac80211: keep mesh ifaces in allmulti mode
Currently a mesh node will not forward a multicast frame if it is not subscribed
to the specific multicast address. This patch addresses the issue and fixes mesh

Luis Carlos Cobo e32f85f7b9 mac80211: fix use of skb->cb for mesh forwarding
Now we deal with mesh forwarding before the 802.11->802.3 conversion, thus
eliminating a few unnecessary steps. The next hop lookup is called from
ieee80211_master_start_xmit() instead of subif_start_xmit(). Until the next hop
is found, RA in the frame will be all zeroes for frames originating from the
device. For forwarded frames, RA will contain the TA of the received frame,
which will be necessary to send a path error if a next hop is not found.

Daniel Drake 80693ceb78 mac80211: automatic IBSS channel selection
When joining an ad-hoc network, the user is currently required to specify
the channel. The network will not be joined otherwise, unless it happens
to be sitting on the currently active channel.

This patch implements automatic channel selection when the user has not
locked the interface onto a specific channel.

yet, currently the maximum provided by the driver or 1 is used.

Johannes Berg 14db74bcc3 mac80211: fix cfg80211 hooks for master interface
The master interface is a virtual interface that is registered
to mac80211, changing that does not seem like a good idea at
the moment. However, since it has no sdata, we cannot accept
any configuration for it. This patch makes the cfg80211 hooks
reject any such attempt.

This patch fixes mac80211 to not use the skb->cb over the queue step
from virtual interfaces to the master. The patch also, for now,
disables aggregation because that would still require requeuing,
will fix that in a separate patch. There are two other places (software
requeue and powersaving stations) where requeue can happen, but that is
not currently used by any drivers/not possible to use respectively.
