9184d9348a [PATCH] ieee80211: Add TKIP crypt->build_iv
This patch adds ieee80211 TKIP build_iv() method to support hardwares
that can do TKIP encryption but relies on ieee80211 layer to build
the IV. It also changes the build_iv() interface to return the key
if possible after the IV is built (this is required by TKIP).

>If encryption is enabled, each fragment payload size is reduced by enough space

>So if you have 1500 bytes of payload with ieee->fts set to 500 without

Text is correct, but in picture (IV,payload,ICV) sits inside SNAP.

a4bf26f30e [PATCH] ieee80211: enable hw wep where host has to build IV
This patch fixes some of the ieee80211 crypto related code so that
instead of having the host fully do crypto operations, the host_build_iv
flag works properly (for WEP in this patch) which, if turned on,
requires the hardware to do all crypto operations, but the ieee80211
layer builds the IV. The hardware also has to build the ICV.

Previously, the host_build_iv flag couldn't be used at all for WEP, and
not alone (with both host_decrypt and host_encrypt disabled) because the
crypto algorithm wasn't assigned. This is also fixed.

I have tested this patch both in host crypto mode and in hw crypto mode
(with the Broadcom chipset).

f0f15ab554 Fixed oops if an uninitialized key is used for encryption.
Without this patch, if you try and use a key that has not been
configured, for example:

% iwconfig eth1 key deadbeef00 [2]

without having configured key [1], then the active key will still be
[1], but privacy will now be enabled.  Transmission of a packet in this
situation will result in a kernel oops.

Per the conversations with folks at OLS, the QoS layer in 802.11
drivers can now result in NETDEV_TX_BUSY being returned when the queue
a packet is targetted for is full.

To implement this, ieee80211_xmit will now call the driver's
is_queue_full to determine if the current priority queue is full.  If
so, NETDEV_TX_BUSY is returned to the kernel and no processing is done
