This patch tries to utilize tuntap rx batching by peeking the tx
virtqueue during transmission, if there's more available buffers in
the virtqueue, set MSG_MORE flag for a hint for tuntap to batch the
packets. The maximum number of batched tx packets were specified
through a module parameter: tx_ba
Backlog were used for tuntap rx, but it can only process 1 packet at
one time since it was scheduled during sendmsg() synchronously in
process context. This lead bad cache utilization so this patch tries
to do some batching before call rx NAPI. This is done through:
- accept MSG_MORE as a hint fro
There are rx_ring_num queues. Each queue will load xdp prog. So

If soc_device_match() is used to check the value of a specific
attribute that is not present for the current SoC, the kernel crashes
with a NULL pointer dereference.
Fix this by explicitly checking for the absence of a needed property,
and considering this a non-match.
Move guts devicetree doc to Documentation/devicetree/bindings/soc/fsl/
since it's used by not only PowerPC but also ARM. And add a specification
for 'little-endian' property.

With this patch, (re)broadcasting on a specific interfaces is avoided:
* No neighbor: There is no need to broadcast on an interface if there
is no node behind it.
* Single neighbor is source: If there is just one neighbor on an
interface and if this neighbor is the one w

A failure during the submission also causes dropped packets.
batadv_interface_tx should therefore also increase the DROPPED counter for
these returns.

kfree_skb assumes that an skb is dropped after an failure and notes that.
consume_skb should be used in non-failure situations. Such information is
important for dropmonitor netlink which tells how many packets were dropped
and where this drop happened.

No caller of batadv_send_skb_to_orig is expecting the results to be -1
(-EPERM) anymore when the skbuff was not consumed. They will instead expect
that the skbuff is always consumed. Having such return code filter is
therefore not needed anymore.

During broadcast queueing, the skb_reset_mac_header() sets the skb

An unicast batman-adv packet cannot be transmitted to a multicast or zero
mac address. So reject incoming packets which still have these classes of
addresses as destination mac address in the outer ethernet header.
