A list containing all group to VCI (and VPI) mapping
entries. Each mapping entry has the following fields
having the exact order :
a) Group Number (4 bytes)
b) VPI (2 bytes)
c) VCI (2 bytes)
A total of 8 bytes for each mapping structure. There is
no separator in between matching structures, nor is a
end-of-string in this whole matching list. The size
of this whole mapping list must be a multiple of 8 bytes.
For Set-Operations, if a user wants to update the mapping
list, he must send the whole mapping list buffer.
