Under uAP mode mwifiex may stop all net tx queues on forwarding
packets. This may stop some tx queues and they never have chance
to be waked up. There is also no need to check tx_pending and
stop queues here. Because local host has such kind of check when
transmitting packets and it's not proper to have forwarding affect
local transmitting.

Steinar reported reallocations of skb->head with IPv6, leading to
a warning in skb_try_coalesce()
It turns out iwl3945 has several problems :
1) skb->truesize is underestimated.
We really consume PAGE_SIZE bytes for a fragment,
not the frame length.
2) 128 bytes of initial headroom is a bit low and forces reallocations.
3) We can avoid consuming a full page for small enough frames.

Unfortunately, the firmware only supports replay counters for
a single GTK in D3, so that we should only upload the last
key and use its replay counters. Since mac80211 key iteration
will walk through the keys in order of their addition, simply
use the same HW key index (1) for all GTKs, thus overwriting
previous ones with newer ones. The replay counters for it are
already used.

Add support to replace an existing entry found in the
vxlan fdb database. The entry in question is identified
by its unicast mac address and the destination information
is changed. If the entry is not found, it is added in the
forwarding database. This is similar to changing an entry
in the neighbour table.
Multicast mac addresses can not be changed with the replace
option.
This is useful for virtual machine migration when the
destination of a target virtual machine changes. The replace
feature can be used instead of delete followed by add.
