[RFC iproute2 PATCH 2/3] iproute: Modify the parser's handling duplicated attributes

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

From: Williams, Mitch A <mitch.a.williams@intel.com>

Modify the parser to keep track of the first of any duplicated attributes,
instead of the last. This is required for VF configuration reporting, where
multiple attributes of the same type are added sequentially.
