Johannes Berg 33e5a2f776 wireless: update radiotap parser
Upstream radiotap has adopted the namespace
proposal David Young made and I then took care
of, for which I had adapted the radiotap parser
as a library outside the kernel. This brings
the in-kernel parser up to speed.

      mac80211: make rx radiotap header more flexible

code was added that tried to align the radiotap header
position in memory based on the radiotap header length.
Quite obviously, that is completely useless.

Instead of trying to do that, use unaligned accesses
to generate the radiotap header. To properly do that,
we also need to mark struct ieee80211_radiotap_header
packed, but that is fine since it's already packed
(and it should be marked packed anyway since its a
wire format).

Johannes Berg aae89831df wireless: radiotap updates
Radiotap was updated to include a "bad PLCP" flag and standardise
the "bad FCS" flag in the "flags" rather than "RX flags" field,
this patch updates Linux to that standard.

Johannes Berg 007e5ddddf wireless: clean up radiotap a bit
No need to pad the header so no constant needed for that,
no need to carry any version number from netbsd nor CVS
IDs from them.

Andy Green dfe6e81dea [MAC80211]: Add get_unaligned to ieee80211_get_radiotap_len
ieee80211_get_radiotap_len() tries to dereference radiotap length without
taking care that it is completely unaligned and get_unaligned()
is required.

Pavel Roskin 6693228da9 [PATCH] Remove comment about IEEE80211_RADIOTAP_FCS
IEEE80211_RADIOTAP_FCS is obsolete and should not be used.  It's no
