Up to six Network CoProcessor interfaces may be installed depending on the configuration of the system. Device names range from ne0 to ne5.

DESCRIPTION

ne is the device driver software that controls the Network CoProcessor board. The ne driver interfaces to the snc_nfsd(8) NFS daemons on the one hand, and to the Network CoProcessor software on the other. The Network CoProcessor software handles all of the network-related processing involved in the NFS file server function. In addition, it handles data link level processing for the remaining networking activities the server may be involved in (such as rlogin, rsh, RPC based programs other than NFS, etc.). With respect to the latter function, the ne driver interfaces to SunOS protocol stacks via the if(4N) general network interface mechanism.

On a kernel configured with the ne driver, the data link layer functionality provided by ne is available as soon as the Network CoProcessor is booted using the neload(8) utility. The NFS server functionality offered by ne does not become available until the snc_nfsd(8) daemons are started.
