[PATCH 1/2] framework/pmd_output: report link speed in Mbps

["Niklas Söderlund" <niklas.soderlund@corigine.com>]

From: Qin Ke <qin.ke@corigine.com>

Link speeds read with get_port_link_speed() have no documented unit.
This leads to issues as different PMD reports speed in both Mbps and
Gbps. The only test-case making use of get_port_link_speed(),
TestSuite_speed_capabilities.py, assumes the speed is returned in Mbps
or an empty string if the speed could not be read.

Document this behavior and extend the get_port_link_speed()
implementations to convert links speeds reported by in Gbps to Mbps.
