The values returned by the driver in the DL_INFO_ACK response are:
The capabilities advertised by the pcn device can be set using dladm(1m). The driver supports a number of parameters whose names begin with en_ (see below). Each of these parameters contains a boolean value that determines if the device advertises that mode of operations. The adv_autoneg_cap parameter controls whether auto-negotiation is performed. If adv_autoneg_cap is set to 0, the driver forces the mode of operation selected by the first non-zero parameter in priority order as shown below:
(highest priority/greatest throughput) en_100fdx_cap 100Mbps full duplex en_10fdx_cap 10Mbps full duplex (lowest priority/least throughput)
All capabilities default to enabled. Note that changing any capability parameter causes the link to go down while the link partners renegotiate the link speed/duplex using the newly changed capabilities.
