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
on the frame.

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).

Allow drivers to fix an issue when using wpa_supplicant with WEP.

The problem is introduced by the hwcrypto patch. We changed indicator of
the encryption request from the upper layer (i.e. wpa_supplicant):

In the original host based crypto the driver could use: crypt &&
crypt->ops.

In the new hardware based crypto, the driver should use the flags
specified in ieee->sec.encrypt.
