When a device is configured for AP mode and it is configured for
WEP then the keys are plumbed first, followed by AP configuration.
During configuration a down command is given to the firmware which
will clear the configured keys. This patch reprograms the WEP keys

These drivers use 9100-byte receive buffers, thus allocating an skb requires
an O(3) memory allocation. Under heavy memory loads and fragmentation, such
a request can fail. Previous versions of the driver have dropped the packet
and reused the old buffer; however, the new version introduced a bug in that
it released the old buffer before trying to allocate a new one. The previous
method is implemented here. The skb is unmapped before any attempt is made to
allocate another.

In case the rate mask for one of the modulations was zero the
max rate idx for that modulation was set to 32 (BITS_PER_LONG).
This is bad as it would later lead to an out of bounds access
to the expected tpt table. In most cases there was no real effect
as the expected tpt was set to 0 and this led to avoiding the
modulation effectively.
Fix the out of bounds access and explicitly skip the modulation
in case there's no rate allowed in it.
