[PATCH] Driver Core: fis bus rescan devices race
bus_rescan_devices_helper() does not hold the dev->sem when it checks for
!dev->driver(). device_attach() holds the sem, but calls again
device_bind_driver() even when dev->driver is set.
What happens is that a first device_attach() call (module insertion time)
is on the way binding the device to a driver. Another thread calls
bus_rescan_devices(). Now when bus_rescan_devices_helper() checks for
dev->driver it is still NULL 'cos the the prior device_attach() is not yet
finished. But as soon as the first one releases the dev->sem the second
device_attach() tries to rebind the already bound device again.
device_bind_driver() does this blindly which leads to a corrupt
driver->klist_devices list (the device links itself, the head points to the
device). Later a call to device_release_driver() sets dev->driver to NULL
and breaks the link it has to itself on knode_driver. Rmmoding the driver
later calls driver_detach() which leads to an endless loop 'cos the list
head in klist_devices still points to the device. And since dev->driver is
NULL it's stuck with the same device forever. Boom. And rmmod hangs.
Very easy to reproduce with new-style pcmcia and a 16bit card. Just loop
modprobe <pcmcia-modules> ;cardctl eject; rmmod <card driver, pcmcia
modules>.
Easiest fix is to check if the device is already bound to a driver in
device_bind_driver(). This avoids the double binding.

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).
