As of r347221 the iflib legacy interrupt mode setup assumes that drivers perform both receive and transmit processing from the interrupt handler. This assumption is invalid in the vmxnet3 driver, so introduce the IFLIB_SINGLE_IRQ_RX_ONLY flag to make iflib avoid tx processing in the interrupt handler.
