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 = ð_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);
}
