Subject: [PATCH] Removed MDL/TEI management configuration warning message.

Some telco switches send out MDL messages even though they are configured
for PTP.  Usually they are checking for assigned TEI's.  Since these
switches periodically poll for assigned TEI's, the message needlessly
fills up log files.

* Changed message warning level to a normal debug message level and
reworded.

(closes issue PRI-137)
