A method for communication between a network interface adapter and a host processor coupled thereto includes writing information using the network interface adapter to a location in a memory accessible to the host processor. Responsive to having written the information, the network interface adapter places an event indication in an event queue accessible to the host processor. It then asserts an interrupt of the host processor that is associated with the event queue, so as to cause the host processor to read the event indication and, responsive thereto, to process the information written to the location.
