Commit 24bbaf6 ("[lotest] Allow loopback testing on shared networks")
introduced a regression in which loopback testing packets would be
accepted from any network device. This produces unexpected results,
such as VLAN loopback testing succeeding even when incorrectly using
the underlying trunk device as either transmitter or receiver.
Fix by discarding any loopback testing packets which arrive on a
network device other than the current loopback testing receiver.

Allow for extraneous packets to be received during loopback testing,
and so permit loopback tests to be performed when ports are connected
to a switch (rather than requiring ports to be directly connected with
a loopback cable).

Include a sequence number as the first four bytes of the loopback test
packet payload. When a content mismatch occurs, this gives some
information about the source of the mismatched packet.

It can sometimes be awkward to prevent additional packets from being
received during a loopback test. Allow such additional packets to be
present without terminating the test.

Allow the link layer to directly report whether or not a packet is
multicast or broadcast at the time of calling pull(), rather than
relying on heuristics to determine this at a later stage.

FCoE requires the use of fabric-provided MAC addresses, which breaks
the assumption that the net device's MAC address is implicitly the
source address for net_tx() and the (unicast) destination address for
net_rx().
