In user-space we specify a list of connections as a bit-mask with the assumption that a list such is indexed as indicated below. end0:3:3:1:1 = 1 end0:3:3:2:3 = 2 end0:3:3:3:4 = 4 Current code assigns bitmask ids based on the order of discovery, however user-space has no idea what the order of discovery is. This patch sorts the linked list of connections associated with the loopback driver and assigns a bit-id based on the sorted list - not the order of discovery. This change therefore enforces the end-users idea that end0:3:3:1:1 above is always denoted by bit 1 - even if from the AP's perspective it was the last entry discovered.
