program number:
ETHERPROG
xdr routines:
xdr_etherstat(xdrs, es)
XDR ∗xdrs;
struct etherstat ∗es;
xdr_etheraddrs(xdrs, ea)
XDR ∗xdrs;
struct etheraddrs ∗ea;
xdr_etherhtable(xdrs, hm)
XDR ∗xdrs;
struct etherhmem ∗∗hm;
xdr_etherhmem(xdrs, hm)
XDR ∗xdrs;

XDR ∗xdrs;
struct etherhmem ∗hm;
xdr_addrmask(xdrs, am)
XDR ∗xdrs;
struct addrmask ∗am;

Xdr_etherhmem processes a single etherhmem structure.  Xdr_etherhtable processes an array of HASHSIZE ∗struct etherhmems. The ∗∗etherhmem field of etheraddrs is actually a hashtable, that is, it is a pointer to an array of HASHSIZE hmem pointers. 

procs:

no args, returns struct etherstat
ETHERPROC_ON
no args or results, puts server in promiscuous mode
ETHERPROC_OFF
no args or results, puts server in promiscuous mode
ETHERPROC_GETSRCDATA
no args, returns struct etheraddrs with information
about source of packets
ETHERPROC_GETDSTDATA
no args, returns struct etheraddrs with information
about destination of packets
ETHERPROC_SELECTSRC
takes struct mask as argument, no results
sets a mask for source
ETHERPROC_SELECTDST
takes struct mask as argument, no results
sets a mask for dst
ETHERPROC_SELECTPROTO
takes struct mask as argument, no results
sets a mask for proto
ETHERPROC_SELECTLNTH
takes struct mask as argument, no results
sets a mask for lnth
