The ixgbe driver functions include controller initialization, frame transmit and receive, promiscuous and multicast support, and error recovery and reporting.
The ixgbe driver supports the following Intel 10-Gigabit PCI Express Ethernet controllers:
The ixgbe driver and hardware support auto-negotiation, a protocol specified by the IEEE 802.3ae specification.
The ixgbe driver is managed by the dladm(1M) command line utility, which allows VLANs to be defined on top of ixgbe instances and for ixgbe instances to be aggregated. See dladm(1M) for more details.
You must send an explicit DL_ATTACH_REQ message to associate the opened stream with a particular device (PPA). The PPA ID is interpreted as an unsigned integer data type and indicates the corresponding device instance (unit) number. The driver returns an error (DL_ERROR_ACK) if the PPA field value does not correspond to a valid device instance number for the system. The device is initialized on first attach and de-initialized (stopped) at last detach.
The values returned by the driver in the DL_INFO_ACK primitive in response to your DL_INFO_REQ are:
Once in the DL_ATTACHED state, you must send a DL_BIND_REQ to associate a particular SAP with the stream.
