The network configuration is specified by declaring
and initializing the rtems_bsdnet_configuration
structure.
The structure entries are described in the following table.
If your application uses BOOTP to obtain network configuration
information and if you are happy with the default values described
below, you need to provide only the first two entries in this structure.
struct rtems_bsdnet_ifconfig *ifconfig
A pointer to the first configuration structure of the first network
device. This structure is described in the following section.
You must provide a value for this entry since there is no default value for it.
void (*bootp)(void)
This entry should be set to rtems_bsdnet_do_bootp
if your application will use BOOTP to obtain network configuration information.
It should be set to NULL
if your application does not use BOOTP.
int network_task_priority
The priority at which the network task and network device
receive and transmit tasks will run.
If a value of 0 is specified the tasks will run at priority 100.
unsigned long mbuf_bytecount
The number of bytes to allocate from the heap for use as mbufs.
If a value of 0 is specified, 64 kbytes will be allocated.
unsigned long mbuf_cluster_bytecount
The number of bytes to allocate from the heap for use as mbuf clusters.
If a value of 0 is specified, 128 kbytes will be allocated.
char *hostname
The host name of the system.
If this, or any of the following, entries are NULL the value
may be obtained from a BOOTP server.
char *domainname
The name of the Internet domain to which the system belongs.
char *gateway
The Internet host number of the network gateway machine,
specified in `dotted decimal' (129.128.4.1) form.
char *log_host
The Internet host number of the machine to which syslog messages
will be sent.
char *name_server[3]
The Internet host numbers of up to three machines to be used as
Internet Domain Name Servers.
int port
The I/O port number (ex: 0x240) on which the external Ethernet
can be accessed.
int irno
The interrupt number of the external Ethernet controller.
int bpar
The address of the shared memory on the external Ethernet controller.
