A value representing the PORT's connection policies desired in
the node. The value of 'pc-mac-lct' (i.e. PCM MAC LinkConfidence
Test) is a term used in the PC_MAC_LCT Flag. The value of
'pc-mac-loop' is a term used in the PC_MAC_LOOP flag.
The value is a sum. This value initially takes the value zero,
then for each PORT policy, 2 raised to a power is added to the
sum. The powers are according to the following table:
Policy Power
------ -----
pc-mac-lct 0
pc-mac-loop 1
