* mlx4: replace the dma_sync_single_range_for_cpu/device APIFUJITA Tomonori2010-02-191-4/+4
| | | | | | | | | | | | | There are only two users of the dma_sync_single_range_for_cpu/device API in mainline (mlx4 and ssb). The dma_sync_single_range_for_cpu/device API has never been documented and the dma_sync_single_for_cpu/device API also support a partial sync. This converts mlx4 to use the dma_sync_single_for_cpu/device API (preparations for the removal of the dma_sync_single_range_for_cpu/device API).

* | mlx4_en: Not using Shared Receive QueuesYevgeny Petrilin2009-08-061-60/+17
| | | | | | | | | | | | | | | | | | We use 1:1 mapping between QPs and SRQs on receive side, so additional indirection level not required. Allocated the receive buffers for the RSS QPs. Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: David S. Miller <davem@davemloft.net>
* | mlx4_en: Using real number of rings as RSS map sizeYevgeny Petrilin2009-08-061-27/+11
|/ | | | | | | | | There is no point in using more QPs then actual number of receive rings. If the RSS function for two streams gives the same result modulo number of rings, they will arrive to the same RX ring anyway.

* mlx4_en: Remove redundant refill code on RXYevgeny Petrilin2009-06-211-96/+0
| | | | | | | | | Our RX rings are always full, there is no need to check whether we need to fill them or not. If we fail to allocate a new socket buffer, the incoming packet is dropped an the ring remains full. Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: David S.

| | | | | | | | | | For each debug message, the message will show interface name in case that the net device was registered, and PCI bus ID with port number if we were not registered yet. Messages that are not port/netdev specific stayed in the old format Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: David S. Miller <davem@davemloft.net>
* mlx4_en: Fix partial rings featureYevgeny Petrilin2009-05-251-26/+45
| | | | | | | | | In case of allocation failure, the actual ring size is rounded down to nearest power of 2. The remaining descriptors are freed. The CQ and SRQ are allocated with the actual size and the mask is updated. Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: David S. Miller <davem@davemloft.net>

* mlx4_en: Assign dummy event handler for TX queueYevgeny Petrilin2009-04-211-6/+0

* mlx4_en: Fix error handling while activating RX ringsYevgeny Petrilin2009-04-211-2/+4
| | | | | | | | | In case of failure of either srq creation or page allocation, the cleanup code handled the failed ring as well, and tried to destroy resources that where not allocated. Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: David S. Miller <davem@davemloft.net>
* workqueue: add to_delayed_work() helper functionJean Delvare2009-04-021-1/+1
| | | | | | | | | | | | | | | | | | | It is a fairly common operation to have a pointer to a work and to need a pointer to the delayed work it is contained in. In particular, all delayed works which want to rearm themselves will have to do that. So it would seem fair to offer a helper function for this operation.

* net: Remove redundant NAPI functionsBen Hutchings2009-01-211-2/+2
| | | | | | | | | | | Following the removal of the unused struct net_device * parameter from the NAPI functions named *netif_rx_* in commit 908a7a1, they are exactly equivalent to the corresponding *napi_* functions and are therefore redundant.

* net: Remove unused netdev arg from some NAPI interfaces.Neil Horman2008-12-221-2/+2
| | | | | | | | | | When the napi api was changed to separate its 1:1 binding to the net_device struct, the netif_rx_[prep|schedule|complete] api failed to remove the now vestigual net_device structure parameter. This patch cleans up that api by properly removing it.. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* mlx4: fix error path in drivers/net/mlx4/en_rx.cIngo Molnar2008-11-251-1/+2
| | | | | | | | | | | | | | | | | | | | | this warning: drivers/net/mlx4/en_rx.c: In function ‘mlx4_en_activate_rx_rings’: drivers/net/mlx4/en_rx.c:412: warning: ‘err’ may be used uninitialized in this function Triggers because 'err' is uninitialized in the following input conditions: priv->rx_ring_num is zero and mlx4_en_fill_rx_buffers() fails. But even if ->rx_ring_num is nonzero, 'err' will be zero if mlx4_en_fill_rx_buffers() fails and mlx4_en_activate_rx_rings() returns success - incorrectly. So it's best to keep the error code uptodate on mlx4_en_fill_rx_buffers() calls as well. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: David S. Miller <davem@davemloft.net>
* drivers/net: Kill now superfluous ->last_rx stores.David S. Miller2008-11-031-2/+0
| | | | | | | | | | | | | The generic packet receive code takes care of setting netdev->last_rx when necessary, for the sake of the bonding ARP monitor. Drivers need not do it any more. Some cases had to be skipped over because the drivers were making use of the ->last_rx value themselves. Signed-off-by: David S. Miller <davem@davemloft.net>
* mlx4_en: Add driver for Mellanox ConnectX 10GbE NICYevgeny Petrilin2008-10-221-0/+1080
The Mellanox ConnectX can operate as an InfiniBand adapter, as an Ethernet NIC, or as a Fibre Channel (FC) HBA. The kernel has a low-level driver, mlx4_core, which handles multiplexing access to the device, and there is also already an InfiniBad driver, mlx4_ib. This patch adds a new driver, mlx4_en, which implements a standard Ethernet NIC driver.
