2008-07-13dccp: Upgrade NDP count from 3 to 6 bytesGerrit Renker
RFC 4340, 7.7 specifies up to 6 bytes for the NDP Count option, whereas the code is currently limited to up to 3 bytes. This seems to be a relict of an earlier draft version and is brought up to date by the patch. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>
2008-07-08netdev: Move atomic queue state bits into netdev_queue.David S. Miller

2008-07-08net: Delete NETDEVICES_MULTIQUEUE kconfig option.David S. Miller
Multiple TX queue support is a core networking feature. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08netdev: Move _xmit_lock and xmit_lock_owner into netdev_queue.David S. Miller
Accesses are mostly structured such that when there are multiple TX queues the code transformations will be a little bit simpler. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08pkt_sched: Make qdisc_run take a netdev_queue.David S. Miller
This allows us to use this calling convention all the way down into qdisc_restart(). Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08netdev: Make netif_schedule() routines work with netdev_queue objects.David S. Miller
Only plain netif_schedule() remains taking a net_device, mostly as a compatability item while we transition the rest of these interfaces. Everything else calls netif_schedule_queue() or __netif_schedule(), both of which take a netdev_queue pointer. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08netdev: Move gso_skb into netdev_queue.David S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08pkt_sched: Add qdisc_tx_is_noop() helper and use in IPV6.David S. Miller
This indicates if the NOOP scheduler is what is active for TX on a given device. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08net: Clean up explicit ->tx_queue references in link watch.David S. Miller
First, we add a qdisc_tx_changing() helper which returns true if the qdisc attachment is in transition. Second, we remove an assertion warning which is of limited value and is hard to express precisely in a multiqueue environment. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08pkt_sched: Add qdisc_all_tx_empty()David S. Miller
This is a helper function, currently used by IRDA. This is being added so that we can contain and isolate as many explicit ->tx_queue references in the tree as possible. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08pkt_sched: Add qdisc_reset_all_tx().David S. Miller
Isolate callers that want to simply reset all the TX qdiscs from the details of TX queues. Use this in the ISDN code. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08netdev: Move next_sched into struct netdev_queue.David S. Miller
We schedule queues, not the device, for output queue processing in BH. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08pkt_sched: Kill stats_lock member of struct Qdisc.David S. Miller
It is always equal to qdisc->dev_queue->lock Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08netdev: Kill qdisc_ingress, use netdev->rx_queue.qdisc instead.David S. Miller
Now that our qdisc management is bi-directional, per-queue, and fully orthogonal, there is no reason to have a special ingress qdisc pointer in struct net_device. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08netdev: Move rest of qdisc state into struct netdev_queueDavid S. Miller
Now qdisc, qdisc_sleeping, and qdisc_list also live there. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08netdev: The ingress_lock member is no longer needed.David S. Miller
Every qdisc is assosciated with a queue, and in the case of ingress qdiscs that will now be netdev->rx_queue so using that queue's lock is the thing to do. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08netdev: Move queue_lock into struct netdev_queue.David S. Miller
The lock is now an attribute of the device queue. One thing to notice is that "suspicious" places emerge which will need specific training about multiple queue handling. They are so marked with explicit "netdev->rx_queue" and "netdev->tx_queue" references. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08pkt_sched: Remove 'dev' member of struct Qdisc.David S. Miller
It can be obtained via the netdev_queue. So create a helper routine, qdisc_dev(), to make the transformations nicer looking. Now, qdisc_alloc() now no longer needs a net_device pointer argument. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08netdev: Create netdev_queue abstraction.David S. Miller
A netdev_queue is an entity managed by a qdisc. Currently there is one RX and one TX queue, and a netdev_queue merely contains a backpointer to the net_device. The Qdisc struct is augmented with a netdev_queue pointer as well. Eventually the 'dev' Qdisc member will go away and we will have the resulting hierarchy: net_device --> netdev_queue --> Qdisc Also, qdisc_alloc() and qdisc_create_dflt() now take a netdev_queue pointer argument.

2008-07-08vlan: avoid header copying and linearisation where possiblePatrick McHardy
- vlan_dev_reorder_header() is only called on the receive path after calling skb_share_check(). This means we can use skb_cow() since all we need is a writable header. - vlan_dev_hard_header() includes a work-around for some apparently broken out of tree MPLS code. The hard_header functions can expect to always have a headroom of at least there own hard_header_len available, so the reallocation check is unnecessary. - __vlan_put_tag() can use skb_cow_head() to avoid the skb_unshare() copy when the header is writable.

2008-07-08vlan: TCI related type and naming cleanupsPatrick McHardy
The VLAN code contains multiple spots that use tag, id and tci as identifiers for arguments and variables incorrectly and they actually contain or are expected to contain something different. Additionally types are used inconsistently (unsigned short vs u16) and identifiers are sometimes capitalized. - consistently use u16 for storing TCI, ID or QoS values - consistently use vlan_id and vlan_tci for storing the respective values - remove capitalization - add kdoc comment to netif_hwaccel_{rx,receive_skb} Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2008-07-08vlan: move struct vlan_dev_info to private headerPatrick McHardy

2008-07-08vlan: uninline __vlan_hwaccel_rxPatrick McHardy
The function is huge and included at least once in every VLAN acceleration capable driver. Uninline it; to avoid having drivers depend on the VLAN module, the function is always built in statically when VLAN is enabled. With all VLAN acceleration capable drivers that build on x86_64 enabled, this results in: text data bss dec hex filename 6515227 854044 343968 7713239 75b1d7 vmlinux.inlined 6505637 854044 343968 7703649 758c61 vmlinux.uninlined ---------------------------------------------------------- -9590 Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2008-07-08vlan: fix network_header/mac_header adjustmentsPatrick McHardy
Lennert Buytenhek points out that the VLAN code incorrectly adjusts skb->network_header to point in the middle of the VLAN header and additionally tries to adjust skb->mac_header without checking for validity. The network_header should not be touched at all since we're only adding headers in front of it, mac_header adjustments are not necessary at all.

2008-07-05net-sched: add dynamically sized qdisc class hash helpersPatrick McHardy
Currently all qdiscs which allow to create classes uses a fixed sized hash table with size 16 to hash the classes. This causes a large bottleneck when using thousands of classes and unbound filters.

2008-07-05vlan: Add GVRP supportPatrick McHardy
Add GVRP support for dynamically registering VLANs with switches. By default GVRP is disabled because we only support the applicant-only participant model, which means it should not be enabled on vlans that are members of a bridge. Since there is currently no way to cleanly determine that, the user is responsible for enabling it. The code is pretty small and low impact, its wrapped in a config option though because it depends on the GARP implementation and the STP core.

Two special cases here - one is rxrpc - I put init_net there explicitly, since we haven't touched this part yet.
