[SK_BUFF]: unions of just one member don't get anything done, kill them

2007-04-26T05:26:20+00:00

Renaming skb->h to skb->transport_header, skb->nh to skb->network_header and
skb->mac to skb->mac_header, to match the names of the associated helpers
(skb[_[re]set]_{transport,network,mac}_header).

[SK_BUFF]: Introduce skb_transport_header(skb)

2007-04-26T05:25:31+00:00

For the places where we need a pointer to the transport header, it is
still legal to touch skb->h.raw directly if just adding to,
subtracting from or setting it to another layer header.

[SK_BUFF]: Introduce ipv6_hdr(), remove skb->nh.ipv6h

2007-04-26T05:25:14+00:00

Now the skb->nh union has just one member, .raw, i.e. it is just like the
skb->mac union, strange, no? I'm just leaving it like that till the transport
layer is done with, when we'll rename skb->mac.raw to skb->mac_header (or
->mac_header_offset?), ditto for ->{h,nh}.

[SK_BUFF]: Use skb_reset_network_header where the return of __pskb_pull was being used

2007-04-26T05:24:49+00:00

It returns skb->data, so we can just use skb_reset_network_header after it.

[SK_BUFF]: Use skb_reset_network_header in skb_push cases

2007-04-26T05:24:47+00:00

skb_push updates and returns skb->data, so we can just call
skb_reset_network_header after the call to skb_push.

[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.
