Several bits of code want to know "is this the last SKB in a queue", and all of them implement this by hand. Provide an common interface to make this check. Signed-off-by: -

Check in dequeue_skb() the state of tx_queue for requeued skb to save on locking and re-requeuing, and possibly remove the current check in qdisc_run(). Based on the idea of Alexander Duyck. Signed-off-by:

There is no reason to call into the complicated qdiscs just to remember the last SKB where we found the device blocked. The SKB is outside of the qdiscs realm at this point. Signed-off-by: -

This patch add support for keeping an additional character alias associated with an network interface. This is useful for maintaining the SNMP ifAlias value which is a user defined value. Routers use this to hold information like which circuit or line it is connected to. It is just an arbitrary text label on the network device. There are two exposed interfaces with this patch, the value can be read/written either via netlink or sysfs. This could be maintained just by the snmp daemon, but it is more generally useful for other management tools, and the kernel is good place to act as an agreed upon interface to store it.

Phonet endpoints are bound to individual ports. This provides a /proc/sys/net/phonet (or sysctl) interface for selecting the range of automatically allocated ports (much like the ip_local_port_range with IPv4). Signed-off-by:

As discovered by Timo Teräs, the currently xfrm_state_walk scheme is racy because if a second dump finishes before the first, we may free xfrm states that the first dump would walk over later. This patch fixes this by storing the dumps in a list in order to calculate the correct completion counter which cures this problem. I've expanded netlink_cb in order to accomodate the extra state related to this. It shouldn't be a big deal since netlink_cb is kmalloced for each dump and we're just increasing it by 4 or 8 bytes.

The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) / (d)) but is perhaps more readable.

The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) / (d)) but is perhaps more readable. In the case of the file drivers/atm/eni.c, I am a little bit suspicious of the -1 at the end of the affected expression. Please check that that is what is wanted.
