bier_fmask : The BIER fmask
The BIER fmask contains the bitString that is applied to packets that egress towards the next-hop. As such the fmask is part of the rewrite (adj) for that next-hop. It it thus an extension of the next-hop and in no way associated with the bit-position(s) that are reachable through it. Fmasks are thus shared by bit-positions that egress throught the same nh (BFR-NBR). Deag fmasks are also shread in the event that a router has local bit-positions. This is necessary to prevent the router recieving two copies of each packet. Consequently it also means that they share the same disposition data for the global data. A struct that represents the reference counting of the bits

An outgoing BIER mask.
aka forwarding bit mask (in the RFCs)
This mask's function is two-fold 1 - it is logical-AND with the input packet header to produce the output packet header 2 - it is logical NAND with the input packet header to modify the bit-mask for the next lookup
