Networking under kvm works best if we allocate a per-vCPU RX and TX
queue in a virtual NIC. This requires a per-vCPU queue on the host side.

It is now safe to increase the maximum number of queues.
Preceding patches:
	net: allow large number of rx queues
  	tuntap: Reduce the size of tun_struct by using flex array
	tuntap: Publish tuntap max queue length as module_param

	made sure this won't cause failures due to high order memory
allocations. Increase it to 256: this is the max number of vCPUs
KVM supports.
