This patch adds a host_strip_iv_icv flag to ieee80211 which indicates that
ieee80211_rx should strip the IV/ICV/other security features from the payload.
This saves on some memmove() calls in the driver and seems like something that
belongs in the stack as it can be used by bcm43xx, ipw2200, and zd1211rw

I will submit the ipw2200 patch separately as it needs testing.

This patch also adds some sensible variable reuse (idx vs keyidx) in
ieee80211_rx

ieee80211_rx_any is new to 2.6.18-rc1, even though it appears this function
was never completed:

http://lists.sipsolutions.net/pipermail/softmac-dev/2006-February/000103.html

This patch changes ieee80211_rx_any to always claim the skb, which avoids
further driver complexity and the possibility of leaking management frames.
It also exports the function so that people can actually use it.

This adds a flag to the ieee80211_network structure which indicates whether
the stored erp_value is valid (a check against 0 is not enough, since an ERP
of 0 is valid and very meaningful).

I also added the ERP IE bit-definitions to ieee80211.h.

This is needed by some upcoming softmac patches.

Attached are two small patches for include/net/ieee80211.h to prepare
for later submission of code to implement a user-space daemon that
supplies 802.11 regulatory information.

The first change adds a bit indicating that 802.11h rules are to be
applied to a channel. As discussed earlier in this list, a single bit
is unlikely to be sufficient; however, at this time I have been unable
to find any regulations implementing differences between 802.11a and
802.11h other than DFS, radar detection and passive scanning. A single
bit is thus sufficient to convey to the driver that these rules should
be obeyed.

The second change adds comments to the freq and max_power fields of
struct ieee80211_channel to indicate the units that are used.

This patch finishes of the partially-complete shared key authentication
implementation in softmac.

The complication here is that we need to encrypt a management frame during
the authentication process. I don't think there are any other scenarios where
this would have to happen.

To get around this without causing too many headaches, we decided to just use
software encryption for this frame. The softmac config option now selects
IEEE80211_CRYPT_WEP so that we can ensure this available. This also involved
a modification to some otherwise unused ieee80211 API.

This patch creates two functions ieee80211_wx_set_auth and
ieee80211_wx_get_auth that can be used by drivers for the wireless
extension handlers instead of writing their own, if the implementation
should be software only.

These patches enable using bcm43xx devices with WPA and this seems (as

and softmac's ieee80211 left.

Fix TKIP, repeated fragmentation problem, and payload_size reporting

1. TKIP encryption
    Originally, TKIP encryption issues msdu + mpdu encryption on every
    fragment. Change the behavior to msdu encryption on the whole
    packet, then mpdu encryption on every fragment.

2. Avoid repeated fragmentation when !host_encrypt.
    We only need do fragmentation when using host encryption. Otherwise
    we only need pass the whole packet to driver, letting driver do the
    fragmentation.

3. change the txb->payload_size to correct value
    FW will use this value to determine whether to do fragmentation. If
    we pass the wrong value, fw may cut on the wrong bound which will
    make decryption fail when we do host encryption.

NOTE:  This requires changing drivers (hostap) that have
extra_prefix_len used within them (structure member name change).
