Linux 5.6 To Bring FQ-PIE Packet Scheduler To Help Fight Bufferbloat
In addition to WireGuard being part of "net-next" as the networking subsystem material targeting the upcoming Linux 5.6 cycle, there is another big last minute addition to the networking space: the Flow Queue PIE packet scheduler has been merged.
