ABSTRACT:
A network interface unit includes an interface memory coupled to a host memory of a network station, the network station also hosting the network interface unit. The host memory is operable to store a plurality of data frames and a plurality of transmit frame descriptors identifying the plurality of data frames. The network further includes a controller to fetch a first transmit frame descriptor from the host memory and to enable a first transmission of at least one portion of a first data frame in response to the first transmit frame descriptor and to fetch a next transmit frame descriptor from the host memory prior to completion of the first transmission. The controller further is operable to reuse at least the first transmit frame descriptor to enable a retransmission of the at least one portion of the first data frame in response to an absence of an acknowledgment of the first transmission.
