NAME
     lmc - Lan Media Corporation SSI/HSSI/DS3 card device driver

SYNOPSIS
     lmc* at pci? dev ? function ?

DESCRIPTION
     The lmc driver provides support for the Lan Media Corporation SSI, HSSI,
     and DS3 PCI WAN adapters based on the DEC 21140 ethernet chip (with sup-
     porting chips to handle the HDLC framing, and synchronous serial inter-
     face.)  The intent is to provide a synchronous serial link with HDLC
     framing at speeds of up to 10Mbps (for the SSI card), 52Mbps (for the
     HSSI card) and DSX jacks for 45Mbps operation without a CSU/DSU (DS3
     card).

     The card will automatically use HDLC framing and defaults to external
     clock source.  It should be configured as any point-to-point link.
