Prasad Pandit 00f3fcef19 migration: refactor channel discovery mechanism ... The various logical migration channels don't have a standardized way of advertising themselves and their connections may be seen out of order by the migration destination. When a new connection arrives, the incoming migration currently make use of heuristics to determine which channel it belongs to. The next few patches will need to change how the multifd and postcopy capabilities interact and that affects the channel discovery heuristic. Refactor the channel discovery heuristic to make it less opaque and simplify the subsequent patches.
