Subject: [PATCH net-next] Increase limit of macvtap queues

Macvtap should be compatible with tuntap for maximum number
of queues. '1059590254fa9dce9cafc4f07d1103dbec415e76' removes
the limitation and increases number of queues in tuntap.
Now, Its safe to increase number of queues in Macvtap as well.
