From faf19bd8bdb1a6ca0dd98843cd09fd96b1f2f901 Mon Sep 17 00:00:00 2001
From: padkrish <padkrish@cisco.com>

Subject: [PATCH] VDP: Support in VDP22 for correct error code/status to
vdptool
This commit has the following changes:
a. Returning the status or error code to vdptool for the error cases. Errors
can be Tx error, invalid parameters, incorrect configuration etc. The vdptool
is modified to print the error messages from lldpad.
b. Modify the vdptool option from set-tlv/get-tlv to set-vsi/get-vsi. The
vdptool man page document is also modified accordingly.
c. Re-arrange the definitions in header files.
d. Fix some formatting issues.
