There was a buffer overflow in the original code. rf_path was 2 and it should
have been only 0 or 1.
I don't have the hardware for this, so I can't test it.
Looking at the code, there are two almost identical sections for updating the
hal variables. The first one was clearly wrong and had the array overflow as
well. The second one looked correct. I decided to use the second section as
is except for whitespace changes.
The differences between the two original sections:
1) The second one had more debug output.
2) The second one looped over rf_path instead of corrupting data.
3) The second one had these additional assigments.
if (rf_path == 0) {
priv->TxPowerLevelOFDM24G[i] = priv->RfTxPwrLevelOfdm1T[rf_path][i] ;
priv->TxPowerLevelCCK[i] = priv->RfTxPwrLevelCck[rf_path][i];
}

This patch removes the (ugly and racy) packet receiving thread and the
kernel socket usage. Instead, packets are received directly by registering
the ethernet type and handling skbs instead of self-allocated buffers.
Some consequences and comments:
* we don't copy the payload data when forwarding/sending/receiving data
anymore. This should boost performance.
* packets from/to different interfaces can be (theoretically) processed
simultaneously. Only the big originator hash lock might be in the way.
* no more polling or sleeping/wakeup/scheduling issues when receiving
packets
* this might introduce new race conditions.
* aggregation and vis code still use packet buffers and are not (yet)
converted.
* all spinlocks were converted to irqsave/restore versions to solve
some lifelock issues when preempted. This might be overkill, some
of these locks might be reverted later.
* skb copies are only done if neccesary to avoid overhead
performance differences:
* we made some "benchmarks" with intel laptops.
* bandwidth on Gigabit Ethernet increased from ~500 MBit/s to ~920 MBit/s
* ping latency decresed from ~2ms to ~0.2 ms
I did some tests on my 9 node qemu environment and could confirm that
usual sending/receiving, forwarding, vis, batctl ping etc works.

forw_bcast_list_lock is spin_locked in both process and softirq context.
SoftIRQ calls the spinlock with disabled IRQ and normal process context
with enabled IRQs.
When process context is inside an spin_locked area protected by
forw_bcast_list_lock and gets interrupted by an IRQ, it could happen
that something tries to lock forw_bcast_list_lock again in SoftIRQ
context. It cannot proceed further since the lock is already taken
somewhere else, but no reschedule will happen inside the SoftIRQ
context. This leads to an complete kernel hang without any chance of
resurrection.
All functions called in process context must disable IRQs when they try
to get get that lock to to prevent any reschedule due to IRQs.
