Historically, we've been using the APME bit to determine whether a device
supports wake on a given port or not. However, this bit specifies the
default wake setting, rather than the wake support. Change the behavior so
that we use a flag to keep the capabilities separate from the enablement
while meeting customer requirements.

There was a bitwise operation error in the fdb_add block
that was only allowing FDB types that were not permanent.

This was the opposite of the intent because the hardware
never ages out address these are the _only_ type of addrs
that should be allowed.

This was missed because until recently iproute2 did not
set any bit for this by default. And our test code to
manage FDB entries on embedded devices similarly did not
set these bits.

I am going to chalk this up as a bug and fix it now.

This patch enables ethtool to correctly identify flow control (pause
frame) auto negotiation, as well as disallow enabling it when it is not
supported. The ixgbe_device_supports_autoneg_fc function is exported and
used for this purpose.

There is also one minor cleanup of the device_supports_autoneg_fc by
removing an unnecessary return statement.

This patch removes the queuing that was previously done for L4 packets
as it is not needed. The filter does not provide functionality, and it
is possible that queue setup here could trample settings done else-where
in the driver. (for example it may use a queue which isn't setup.)
Setting of the queue is not required for hardware timestamping and could
have inadverdent side effects.

All packet headers in front of an ethernet header have to be completely
divisible by 2 but not by 4 to make the payload after the ethernet header again
4 bytes boundary aligned.

A packing of 2 is necessary to avoid extra padding at the end of the struct
caused by a structure member which is larger than two bytes. Otherwise the
structure would not fulfill the previously mentioned rule to avoid the
misalignment of the payload after the ethernet header. It may also lead to
leakage of information when the padding it not initialized before sending.

If the skb is fragmented, the checksum must be computed on the
individual fragments, just using skb->data may fail on fragmented
data. Instead of doing linearizing the packet, use the new
batadv_crc32 to do that more efficiently- it should not hurt
replacing the old crc16 by the new crc32.

By adding batadv_send_skb_to_orig() in send.c, we can remove duplicate
code that looks up the next hop and then calls batadv_send_skb_packet().

Furthermore, this prepares the upcoming new implementation of
fragmentation, which requires the next hop to route packets.

Please note that this doesn't entirely remove the next-hop lookup in
routing.c and unicast.c, since it is used by the current fragmentation
code.

Also note that the next-hop info is removed from debug messages in
translation-table.c, since it is looked up elsewhere.

In the event that an association exceeds its max_retrans attempts, we should
send an ABORT chunk indicating that we are closing the assocation as a result.
Because of the nature of the error, its unlikely to be received, but its a nice
clean way to close the association if it does make it through, and it will give
anyone watching via tcpdump a clue as to what happened.

	+ ARP reduction, whereby a bridge-connected VXLAN tunnel endpoint
		answers ARP requests from the local bridge on behalf of
		remote DOVE clients
	+ route short-circuiting (aka L3 switching). Known destination IP
		addresses use the corresponding destination MAC address for
		switching rather than going to a (possibly remote) router first.
	+ netlink notification messages for forwarding table and L3 switching
		misses
