Abstract: An adapter includes a network interface module configured to interface the adapter to a network and a Peripheral Component Interconnect Express (PCIe) interface module configured to interface the adapter to a PCIe bus. The PCIe interface module comprises registers in PCIe extended configuration space. The registers are configured to receive ioctls from the PCIe bus. The adapter also includes an ioctl processing module configured to receive the ioctls from the registers, to perform the ioctls, and to provide results of the ioctls to the registers for provision by the registers to the PCIe bus. The ioctls comprise commands that relate to transceiving of frames by the adapter on the network. The network interface may be Ethernet, Fiber Channel, Infiniband, etc. Examples of the ioctls include retrieving operation or error statistics, setting virtual channel tag and priorities, and setting a protocol address associated with a port of the adapter.
