Re: what is equivalent to ether_setup in 8139too.c as given in LDD page 504

[Denis Kirjanov <kirjanov@xxxxxxxxx>]

This functions are helpers for the generic link layers(L2) params setup.
For example:

 /**
 * ether_setup - setup Ethernet network device
 * @dev: network device
 * Fill in the fields of the device structure with Ethernet-generic values.
 */
void ether_setup(struct net_device *dev)
{
        dev->header_ops         = &eth_header_ops;
        dev->type               = ARPHRD_ETHER;
        dev->hard_header_len    = ETH_HLEN;
        dev->mtu                = ETH_DATA_LEN;
        dev->addr_len           = ETH_ALEN;
        dev->tx_queue_len       = 1000; /* Ethernet wants good queues */
        dev->flags              = IFF_BROADCAST|IFF_MULTICAST;

        memset(dev->broadcast, 0xFF, ETH_ALEN);

}
 or for the FDDI:

static void fddi_setup(struct net_device *dev)
{
        dev->header_ops         = &fddi_header_ops;
        dev->type               = ARPHRD_FDDI;
        dev->hard_header_len    = FDDI_K_SNAP_HLEN+3;   /* Assume
802.2 SNAP hdr len + 3 pad bytes */
        dev->mtu                = FDDI_K_SNAP_DLEN;     /* Assume max
payload of 802.2 SNAP frame */
        dev->addr_len           = FDDI_K_ALEN;
        dev->tx_queue_len       = 100;                  /* Long queues
on FDDI */
        dev->flags              = IFF_BROADCAST | IFF_MULTICAST;

        memset(dev->broadcast, 0xFF, FDDI_K_ALEN);
}
