| * ipv4: remove ip_rt_secret timer (v4)Neil Horman2010-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | A while back there was a discussion regarding the rt_secret_interval timer. Given that we've had the ability to do emergency route cache rebuilds for awhile now, based on a statistical analysis of the various hash chain lengths in the cache, the use of the flush timer is somewhat redundant. This patch removes the rt_secret_interval sysctl, allowing us to rely solely on the statistical analysis mechanism to determine the need for route cache flushes.

| * bnx2: Add prefetches to rx path.Michael Chan2010-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | Add prefetches of the skb and the next rx descriptor to speed up rx path. Use prefetchw() for the skb [suggested by Eric Dumazet]. The rx descriptor is in skb->data which is mapped for streaming mode DMA. Eric Dumazet pointed out that we should not prefetch the data before dma_sync. So we prefetch only if dma_sync is no_op on the system. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| * rps: Various optimizationsEric Dumazet2010-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce ____napi_schedule() helper for callers in irq disabled contexts. rps_trigger_softirq() becomes a leaf function. Use container_of() in process_backlog() instead of accessing per_cpu address. Use a custom inlined version of __napi_complete() in process_backlog() to avoid one locked instruction : only current cpu owns and manipulates this napi, and NAPI_STATE_SCHED is the only possible flag set on backlog. we can use a plain write instead of clear_bit(), and we dont need an smp_mb() memory barrier, since RPS is on, backlog is protected by a spinlock.

| * netpoll: add generic support for bridge and bonding devicesWANG Cong2010-05-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This whole patchset is for adding netpoll support to bridge and bonding devices. I already tested it for bridge, bonding, bridge over bonding, and bonding over bridge. It looks fine now. To make bridge and bonding support netpoll, we need to adjust some netpoll generic code. This patch does the following things: 1) introduce two new priv_flags for struct net_device: IFF_IN_NETPOLL which identifies we are processing a netpoll; IFF_DISABLE_NETPOLL is used to disable netpoll support for a device at run-time; 2) introduce one new method for netdev_ops: ->ndo_netpoll_cleanup() is used to clean up netpoll when a device is removed. 3) introduce netpoll_poll_dev() which takes a struct net_device * parameter; export netpoll_send_skb() and netpoll_poll_dev() which will be used later; 4) hide a pointer to struct netpoll in struct netpoll_info, ditto. 5) introduce ->real_dev for struct netpoll. 6) introduce a new status NETDEV_BONDING_DESLAE, which is used to disable netconsole before releasing a slave, to avoid deadlocks.

| | | | | | | | | | | | | | | | | | | | | | | | | | The driver was calling the set Rx mode function for every multicast filter set by the VF.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | virtio added mergeable buffers mode where 2 bytes of extra info is put after vnet header but before actual data (tun does not need this data). In hindsight, it would have been better to add the new info *before* the packet: as it is, users need a lot of tricky code to skip the extra 2 bytes in the middle of the iovec, and in fact applications seem to get it wrong, and only work with specific iovec layout. The fact we might need to split iovec also means we might in theory overflow iovec max size. This patch adds a simpler way for applications to handle this, and future proofs the interface against further extensions, by making the size of the virtio net header configurable from userspace. As a result, tun driver will simply skip the extra 2 bytes on both input and output. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Acked-by: David S. Miller <davem@davemloft.net>
