Peter Zijlstra 654bed16cf net: packet split receive api
Add some packet-split receive hooks.

For one this allows to do NUMA node affine page allocs. Later on these
hooks will be extended to do emergency reserve allocations for
fragments.

Lennert Buytenhek 04a4bb55bc net: add skb_recycle_check() to enable netdriver skb recycling
This patch adds skb_recycle_check(), which can be used by a network
driver after transmitting an skb to check whether this skb can be
recycled as a receive buffer.

skb_recycle_check() checks that the skb is not shared or cloned, and
that it is linear and its head portion large enough (as determined by
the driver) to be recycled as a receive buffer.  If these conditions
are met, it does any necessary reference count dropping and cleans
up the skbuff as if it just came from __alloc_skb().

This patch fixes mac80211 to not use the skb->cb over the queue step

not currently used by any drivers/not possible to use respectively.

Use a real skb member to store the skb to avoid clashes with qdiscs,

Herbert Xu a59322be07 [UDP]: Only increment counter on first peek/recv
The previous move of the the UDP inDatagrams counter caused each
peek of the same packet to be counted separately.  This may be
undesirable.

This patch fixes this by adding a bit to sk_buff to record whether
this packet has already been seen through skb_recv_datagram.  We
then only increment the counter when the packet is seen for the
first time.

The only dodgy part is the fact that skb_recv_datagram doesn't have
a good way of returning this new bit of information.  So I've added
a new function __skb_recv_datagram that does return this and made
skb_recv_datagram a wrapper around it.

The plan is to eventually replace all uses of skb_recv_datagram with
this new function at which time it can be renamed its proper name.

The intent of the assertion in skb_truesize_check() is to check
for skb->truesize being decremented too much by other code,
resulting in a wraparound below zero.

The type of the right side of the comparison causes the compiler to
promote the left side to an unsigned type, despite the presence of an
explicit type cast.  This defeats the check for negativity.

Ensure both sides of the comparison are a signed type to prevent the
implicit type conversion.

Herbert Xu deea84b0ae [NET]: Fix SKB_WITH_OVERHEAD calculation
The calculation in SKB_WITH_OVERHEAD is incorrect in that it can cause
an overflow across a page boundary which is what it's meant to prevent.
In particular, the header length (X) should not be lumped together with
skb_shared_info.  The latter needs to be aligned properly while the header
has no choice but to sit in front of wherever the payload is.

Therefore the correct calculation is to take away the aligned size of
skb_shared_info, and then subtract the header length.  The resulting
quantity L satisfies the following inequality:

	SKB_DATA_ALIGN(L + X) + sizeof(struct skb_shared_info) <= PAGE_SIZE

This is the quantity used by alloc_skb to do the actual allocation.

Herbert Xu d9cc20484e [NET] skbuff: Add skb_cow_head
This patch adds an optimised version of skb_cow that avoids the copy if
the header can be modified even if the rest of the payload is cloned.

This can be used in encapsulating paths where we only need to modify the
header.  As it is, this can be used in PPPOE and bridging.

Herbert Xu c6c6e3e05c [NET]: Update comments for skb checksums
Rusty (whose comments we should all study and emulate :) pointed
out that our comments for skb checksums are no longer up-to-date.
So here is a patch to

1) add the case of partial checksums on input;
2) update partial checksum case to mention csum_start/csum_offset;
3) mention the new IPv6 feature bit.

Peter P Waskiewicz Jr f25f4e4480 [CORE] Stack changes to add multiqueue hardware support API
Add the multiqueue hardware device support API to the core network
stack.  Allow drivers to allocate multiple queues and manage them at
the netdev level if they choose to do so.

Added a new field to sk_buff, namely queue_mapping, for drivers to
know which tx_ring to select based on OS classification of the flow.
