| | | | | | | | | | CONFIG_CHELSIO_T1_COUGAR cannot be set (it appears nowhere in any Kconfig files), and the code it protects could never build (cspi.h was never added to the kernel tree).

| | | | | | | | | | | | | | | | | | | | Christoph Lameter mentioned that packets could be dropped in input path because of rp_filter settings, without any SNMP counter being incremented. System administrator can have a hard time to track the problem. This patch introduces a new counter, LINUX_MIB_IPRPFILTER, incremented each time we drop a packet because Reverse Path Filter triggers.

* | net: replace hooks in __netif_receive_skb V5Jiri Pirko2010-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | What this patch does is it removes two receive frame hooks (for bridge and for macvlan) from __netif_receive_skb. These are replaced them with a single hook for both. It only supports one hook per device because it makes no sense to do bridging and macvlan on the same device. Then a network driver (of virtual netdev like macvlan or bridge) can register an rx_handler for needed net device.

* | packet_mmap: expose hw packet timestamps to network packet capture utilitiesScott McMillan2010-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a setting, PACKET_TIMESTAMP, to specify the packet timestamp source that is exported to capture utilities like tcpdump by packet_mmap. PACKET_TIMESTAMP accepts the same integer bit field as SO_TIMESTAMPING. However, only the SOF_TIMESTAMPING_SYS_HARDWARE and SOF_TIMESTAMPING_RAW_HARDWARE values are currently recognized by PACKET_TIMESTAMP. SOF_TIMESTAMPING_SYS_HARDWARE takes precedence over SOF_TIMESTAMPING_RAW_HARDWARE if both bits are set. If PACKET_TIMESTAMP is not set, a software timestamp generated inside the networking stack is used (the behavior before this setting was added).

* | net: add additional lock to qdisc to increase throughputEric Dumazet2010-06-02

The cpu owning __QDISC_STATE_RUNNING bit has same priority to acquire the lock, and cannot dequeue packets fast enough, since it must wait for this lock for each dequeued packet. One solution to this problem is to force all cpus spinning on a second lock before trying to get the main lock, when/if they see __QDISC_STATE_RUNNING already set. The owning cpu then compete with at most one other cpu for the main lock, allowing for higher dequeueing rate. Based on a previous patch from Alexander Duyck. I added the heuristic to avoid the atomic in fast path, and put the new lock far away from the cache line used by the dequeue worker. Also try to release the busylock lock as late as possible. Tests with following script gave a boost from ~50.000 pps to ~600.000 pps on a dual quad core machine (E5450 @3.00GHz), tg3 driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Following changes have been added to enable the adapter to work in NIC partitioning mode where multiple PCI functions of an adapter port can be configured to work as NIC functions. The first function that is enumerated on the PCI bus assumes the role of management function which, besides being able to do all the NIC functionality, can configure other NIC partitions. Other NIC functions can be configured as privileged or non privileged functions. Privileged function can not configure other NIC functions but can do all the NIC functionality including any firmware initialization, chip reset etc. Non privileged functions can do only basic IO. For chip reset etc, it depends on the privilege or management function. 1. Added code to determine PCI function number independent of kernel API. 2. Added Driver - FW version 2.0 support. 3. Changed producer and consumer register offset calculation. 4. Added management and privileged operation modes for npar functions. A module parameter has been added to control it. 5. Added support for configuring the eswitch in the adapter. Signed-off-by: Anirban Chakraborty <anirban.chakraborty@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cut-through design of the receive path means that packets that fail to match the appropriate MAC filter are not discarded at the MAC but are flagged in the completion event as 'to be discarded'. On networks with heavy multicast traffic, this can account for a significant proportion of received packets, so it is worthwhile to recycle the buffer immediately in this case rather than freeing it and then reallocating it shortly after. The only complication here is dealing with a page shared between two receive buffers. In that case, we need to be careful to free the dma mapping when both buffers have been free'd by the kernel. This means that we can only recycle such a page if both receive buffers are discarded. Unfortunately, in an environment with 1500mtu, rx_alloc_method=PAGE, and a mixture of discarded and not-discarded frames hitting the same receive queue, buffer recycling won't always be possible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under certain conditions a PHY may backpressure Falcon B0 in such a way that flushes timeout. In normal circumstances the phy poller would fix the PHY, and the flush could complete. But efx_nic_flush_queues() is always called after efx_stop_all(), so the poller has been stopped. Even if this weren't the case, how long would we have to wait for the poller to fix this? And several callers of efx_nic_flush_queues() are about to reset the device anyway - so we don't need to do anything. Work around this bug by scheduling a reset. Ensure that the MAC is never rewired back into the datapath before the reset runs (we already ignore all rx events anyway).

* | ipv6: get rid of ipip6_prl_lockEric Dumazet2010-06-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As noticed by Julia Lawall, ipip6_tunnel_add_prl() incorrectly calls kzallloc(..., GFP_KERNEL) while a spinlock is held. She provided a patch to use GFP_ATOMIC instead. One possibility would be to convert this spinlock to a mutex, or preallocate the thing before taking the lock. After RCU conversion, it appears we dont need this lock, since caller already holds RTNL Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
