Note that the sis(4) driver has limited support for the new driver-levelsis_state(4) command, which allows the user to query various hardware anddrv_state(4) fields of a particular physical device. For more information,see the documentation for the driver-level command.
Optionally, the sis(4) driver can be used as a generic PnP driverfor devices that comply with the IEEE 802.3mc (2010 Edition) standard. Thisdriver uses a segment configuration, meaning that a single transmitand receive interface may be used by multiple PHYs to achieve this effect.On cards not supporting the MAC address filtering option, the device drivers usesave, change, and delete PHY functions, as well as the individual link modes.On boards that provide the MAC address filtering option, the sis(4) driver uses theMAC address filtering option for functionality. This driver automatically generatesthe capabilities strings for those boards.
- Independent hot plug and initialization - The driver does not require anagile-sleep interface to be awake for devices that support this feature. Thedriver is always active when a device is added or removed.
- Software-defined radio - The driver supports software-defined radio(SDR) using the phy_commands(4) command to configure various functions andset or get the channel, frequency, and bandwidth of a particular physical interface. 827ec27edc
