le - LeMAC Ethernet interface
SYNOPSIS
config_driver le
DESCRIPTION
The le interface provides access to a 10 Mb/s Ethernet network through the LeMAC controller.
The host's Internet address is specified at boot time with an SIOCSIFADDR ioctl. The le interface employs the address resolution protocol
described in arp(7) to map dynamically between Internet and Ethernet addresses on the local network.
The SIOCSPHYSADDR ioctl can be used to change the physical address of the LeMAC. The SIOCRPHYSADDR ioctl can be used to read the physical
address of the LeMAC.
The SIOCADDMULTI and SIOCDELMULTI ioctls can be used to add or delete multicast addresses. The LeMAC recognizes a maximum of 12 multicast
addresses.
The SIOCRDCTRS and SIOCRDZCTRS ioctls can be used to read or ``read and clear'' the Ethernet driver counters. The argument to these two
ioctls is a pointer to a counter structure, ctrreq, found in <net/if.h>.
The SIOCENABLBACK and SIOCDISABLBACK ioctls can be used to enable and disable the interface loopback mode respectively.
EXAMPLES
To obtain the physical address of the adapter, use the SIOCRPHYSADDR ioctl as in the following program example: #include <stdio.h>
/* standard I/O */ #include <errno.h> /* error numbers */ #include <sys/socket.h> /* socket definitions */ #include
<sys/ioctl.h> /* ioctls */ #include <net/if.h> /* generic interface structures */
main() {
int s,i;
struct ifdevea devea;
/* Get a socket */
s = socket(AF_INET,SOCK_DGRAM,0);
if (s < 0) {
perror("socket");
exit(1);
}
strcpy(devea.ifr_name,"le0");
if (ioctl(s,SIOCRPHYSADDR,&devea) < 0) {
perror(&devea.ifr_name[0]);
exit(1);
}
printf("Address is ");
for (i = 0; i < 6; i++)
printf("%X ", devea.default_pa[i] & 0xff);
printf("
");
close(s); }
To enable external loopback, use the SIOCENABLEBACK ioctl as in the following program example: #include <stdio.h> /* standard
I/O */ #include <errno.h> /* error numbers */ #include <sys/socket.h> /* socket definitions */ #include <sys/ioctl.h>
/* ioctls */ #include <net/if.h> /* generic interface structures */
main() {
int s;
struct ifreq data;
/* Get a socket */
s = socket(AF_INET,SOCK_DGRAM,0);
if (s < 0) {
perror("socket");
exit(1);
}
strcpy(data.ifr,"le0");
if (ioctl(s,SIOCENABLEBACK,&data) < 0) {
perror("SIOCENABLEBACK:");
exit(1);
}
close(s); }
ERRORS
The diagnostic error messages contain relevant information provided by the LeMAC. The interface was handed a message with addresses for-
matted in an unsuitable address family, and the packet was dropped. The le driver was unable to allocate memory for internal data struc-
tures. The IRQ for the LeMAC is missing from the CMOS configuration data or is incorrect. The IRQ for the LeMAC is missing from the CMOS
configuration data or is incorrect. Too many multicast requests have been made. The shared memory block for the LeMAC's local RAM buffer
is missing from the CMOS configuration data. The station address PROM on the LeMAC is corrupt or inaccessible. The hardware transmit
queue has been overflowed.
An attempt was made to delete the Ethernet broadcast address of ff-ff-ff-ff-ff.
