can: add private data space for CAN sk_buffs

2013-01-26T15:59:01+00:00

The struct can_skb_priv is used to transport additional information along
with the stored struct can(fd)_frame that can not be contained in existing
struct sk_buff elements.

can_skb_priv is located in the skb headroom, which does not touch the existing
CAN sk_buff usage with skb->data and skb->len, so that even out-of-tree
CAN drivers can be used without changes.

Btw. out-of-tree CAN drivers without can_skb_priv in the sk_buff headroom
would not support features based on can_skb_priv.

The can_skb_priv->ifindex contains the first interface where the CAN frame
appeared on the local host. Unfortunately skb->skb_iif can not be used as this
value is overwritten in every netif_receive_skb() call.

drivers/net: Remove unnecessary k.alloc/v.alloc OOM messages

2012-01-31T21:20:21+00:00

alloc failures use dump_stack so emitting an additional
out-of-memory message is an unnecessary duplication.

Remove the allocation failure messages.

drivers/net: fix up stale paths from driver reorg

2012-01-30T17:54:40+00:00

The reorganization of the driver layout in drivers/net
left behind some stale paths in comments and in Kconfig
help text.  Bring them up to date.  No actual change to
any code takes place here.

net: remove NETIF_F_NO_CSUM feature bit

2011-11-16T22:43:12+00:00

Only distinct use is checking if NETIF_F_NOCACHE_COPY should be
enabled by default. The check heuristics is altered a bit here,
so it hits other people than before. The default shouldn't be
trusted for performance-critical cases anyway.

For all other uses NETIF_F_NO_CSUM is equivalent to NETIF_F_HW_CSUM.

slcan: ldisc generated skbs are received in softirq context

2011-08-11T12:52:57+00:00

As this discussion pointed out

http://marc.info/?l=linux-netdev&m=131257225602375

netdevices that are based on serial line disciplines should use netif_rx_ni()
when pushing received socketbuffers into the netdev rx queue.

Following commit 614851601c121b1320a35757ab88292d6272f906 ("slip: fix NOHZ
local_softirq_pending 08 warning") this patch updates the slcan driver
accordingly.
