The mxfe is a Solaris STREAMS hardware driver supporting the Data Link Provider Interface (dlpi(7P)) over the Macronix 98715 family (including the Lite-On PNIC-II) of Fast Ethernet controllers.
The mxfe driver supports both style 1 and style 2 modes of operation. Physical points of attachment (PPAs) are interpreted as the instance number of the mxfe controller as assigned by the operating system.
The relevant fields returned as part of a DL_INFO_ACK response are:
Maximum SDU is 1500.
Minimum SDU is 0.
DLSAP address length is 8.
MAC type is DL_ETHER.
SAP length value is -2, meaning the physical address component is followed immediately by a 2-byte SAP component within the DLSAP address.
Service mode is DL_CLDLS.
Broadcast address value is the 6–byte Ethernet/IEEE broadcast address (ff:ff:ff:ff:ff:ff).
If the SAP provided is zero, IEEE 802.3 mode is assumed and outbound frames will have the frame payload length written into the type field Likewise, inbound frames with a SAP between zero and 1500 are interpreted as IEEE 802.3 frames and delivered to streams that have bound to SAP zero (the 802.3 SAP).
Special character device
64–bit ELF kernel module (x86).
Driver binary (SPARC).
