User Direct Access Programming Library

This library supports service providers written according to the uDAPL 1.2
specification. Sun provides default service provider modules to support the Tavor
HCA driver.

IP over InfiniBand Driver

The IPoIB driver implements the IETF IPoIB protocol and provides IPoIB services for
all IB-HCA ports present in the system. This driver enables the standard Solaris
TCP/IP stack to operate over Infiniband. The link layer driver encapsulates IPv4/6
packets, adds IB multicast support, extends ARP/ND address resolution, and
changes the network stack to support link addresses greater than 6 bytes.
