pmc_create() calls transport_create(), which sets the open function
for the interface 'iface' to raw_open(), if Layer 2 is used. The
immediate following call of transport_open() calls raw_open(), which
uses the field .ts_label for opening, instead of the field .name
(which is used in the other transport layers). Therefore, the
field .name is copied here into the field .ts_label .
[ RC - Actually ts_label should always be initialized. Made the
assignment of ts_label unconditional, regardless of the choice
of transport layer. ]

This patch changes the receive message parsing code to place each TLV
into the list. A method is introduced that allows attaching TLVs to
the end of the list.
In addition, msg.last_tlv is converted into a pointer to the last item
in the list. Because of this change, the transmit code that uses this
field now allocates a TLV before using it.

In the near future, the transports will need to consult the configuration
database in order to obtain various options. This patch also introduces
the idea of a configuration file into the phc2sys and pmc programs.

Implement pmc_target_port to set a port number, leaving clock identity
unchanged, and pmc_target_all to set clock identity and port number to all
1's.

When phc2sys is started before ptp4l or it is interrupted before ptp4l has
a chance to reply to its query, the "uds: sendto failed: Connection refused"
message is output. This is not an interesting message.
Also, don't output the "failed to send message" error from pmc_send, as
all transports output errors in their send routine.

The callers of those functions are all using ptp_message. As we're going to
return more information (the address), let those functions just fill in the
ptp_message fields directly.
Some minor reshuffling needed to prevent circular header dependencies.

This patch replaces the hard coded wild card target port identity with
a variable initially set to the wild card value. The intent is to allow
the caller to set specific targets.

This patch makes the original behavior of sending the
TLV values for GET actions with a length of zero.
Signed-off-by: Richard Cochran <richardcochran@gmail.com>
This commit makes the GET messages have data bodies, just like the erratum
says to. It really doesn't make sense, but have to do it anyhow. We also
introduce a variable that will enable the legacy behavior of sending
empty bodies.

This patch lets the TLV length field of GET messages come from a
function. For now, the function still results in a length of two,
but the intent is to allow different values later.

When there is a peer speaking PTPv1 in the network we want to silently ignore
the packets instead of flooding system log with error messages. At the same
time we still want to report malformed packets. For that we reuse standard
error numbers and do more fine-grained error reporting in packet processing
routines.
