per-stack

When set to 1, if a UDP socket is connected to an IP address that cannot be accelerated by Onload, or resource restrictions prevent RX acceleration, hand the socket over to the kernel stack.

When this option is disabled the socket remains under the control of Onload. This might be worthwhile because the socket might subsequently be re-connected to an IP address that can be accelerated, or the socket might be intended for TX use only.

When set to 2, hand the socket over on connect() even if the address could have been accelerated.
