[NET] loopback: Panic if registration fails

2007-07-31T09:28:14Z

Because IPv4 and IPv6 both depend on the presence of the loopback device to function, failure in registration the loopback device should be fatal. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[NET]: loopback driver can use loopback_dev integrated net_device_stats

2007-04-26T05:28:52Z

Rusty added a new 'stats' field to struct net_device. loopback driver can use it instead of declaring another struct net_device_stats This saves some memory. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

[SK_BUFF]: Introduce skb_copy_to_linear_data{_offset}

2007-04-26T05:28:29Z

To clearly state the intent of copying to linear sk_buffs, _offset being a overly long variant but interesting for the sake of saving some bytes. Signed-off-by: Arnaldo Carvalho de Melo

[SK_BUFF]: Introduce ip_hdr(), remove skb->nh.iph

[SK_BUFF]: Introduce skb_network_header()

2007-04-26T05:24:59Z

For the places where we need a pointer to the network header, it is still legal to touch skb->nh.raw directly if just adding to, subtracting from or setting it to another layer header. Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

[SK_BUFF]: Introduce skb_reset_network_header(skb)

2007-04-26T05:24:46Z

For the common, open coded 'skb->nh.raw = skb->data' operation, so that we can later turn skb->nh.raw into a offset, reducing the size of struct sk_buff in 64bit land while possibly keeping it as a pointer on 32bit. This one touches just the most simple case, next will handle the slightly more "complex" cases. Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

[SK_BUFF]: Introduce skb_set_mac_header()

2007-04-26T05:24:37Z

For the cases where we want to set skb->mac.raw to an offset from skb->data. Simple cases first, the memmove ones and specially pktgen will be left for later. Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

[ETH]: Make eth_type_trans set skb->dev like the other *_type_trans

2007-04-26T05:24:30Z

One less thing for drivers writers to worry about. Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

[NET] drivers/net/loopback.c: convert to module_init()

[NET]: Can use __get_cpu_var() instead of per_cpu() in loopback driver.

2006-10-20T07:32:41Z

As BHs are off in loopback_xmit(), preemption cannot occurs, so we can use __get_cpu_var() instead of per_cpu() (and avoid a preempt_enable()/preempt_disable() pair) Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller
