[NET] loopback: Panic if registration fails

2007-07-31T09:28:14+00:00

Because IPv4 and IPv6 both depend on the presence of the loopback
device to function, failure in registration the loopback device should
be fatal.

[NET]: loopback driver can use loopback_dev integrated net_device_stats

2007-04-26T05:28:52+00:00

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.

[SK_BUFF]: Introduce skb_copy_to_linear_data{_offset}

2007-04-26T05:28:29+00:00

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.

[SK_BUFF]: Introduce skb_network_header()

2007-04-26T05:24:59+00:00

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.

[SK_BUFF]: Introduce skb_reset_network_header(skb)

2007-04-26T05:24:46+00:00

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.

[SK_BUFF]: Introduce skb_set_mac_header()

2007-04-26T05:24:37+00:00

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.

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

2007-04-26T05:24:30+00:00

One less thing for drivers writers to worry about.

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

2006-10-20T07:32:41+00:00

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)
