Subject: [PATCH] Moving lldp cmd parsing to be above the is_sfp check to take
 precedence

Needed to increase buffer size for this to send app.js

The logical port status is what is returned in the array, for
non-sequential systems we need to map through physToLog rather
than just subtracting 1

physToLog is 1 based! not 0; also fixing up typecasts

Reimplementing using an array of objects to represent ports.
The previous approach of a bitmask of logical ports, was just too
simple on devices such as the SWGT024_V2_0_MANAGED which has
gaps in the port assignments.
