[PATCH 1/5] Adds input keys enumeration

[Peter Warasin <peter@endian.com>]

[-- Attachment #1: filter-raw2packet-usekeys.patch --]
[-- Type: text/plain, Size: 1948 bytes --]

Adds input key enumeration in order to address the fields
with symbols instead of numbers.
Shortens the lines by the use of GET_VALUE()
