Invalid logical speed is displayed for trunk enabled ports when all
ports are down. Also noted that link speed is incorrectly reported
for the units when links are up.
Current code is returning the logical link speed from the last event
from the adapter. In cases where the last link went down, the link
speed in the event was not valid - meaning that although the links
where down the field had a bogus value.
Rework the event handling to qualify the trunk link state before
using the event speed data.
Also correct units on other areas where the logical link speed
was taken from a link event.
