* sfc: Cleanup RX queue informationBen Hutchings2008-09-031-29/+14
| | | | | | | | | Rename efx_nic::rss_queues to the more obvious n_rx_queues Remove efx_rx_queue::used and other stuff that's redundant with it. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* sfc: Remove efx_channel::has_interruptBen Hutchings2008-09-031-11/+5
| | | | | | | | | efx_channel::has_interrupt is redundant with efx_channel::used_flags. Remove efx_test_eventq() because it is now obviously unreachable. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* sfc: Move CPU counting for RSS into a separate function, efx_wanted_rx_queues()Ben Hutchings2008-09-031-25/+35

* sfc: Removed forced inlining of long functionsBen Hutchings2008-09-031-1/+1
| | | | | | | | | gcc will automatically inline static functions with only one caller, and may inline other functions depending on the kernel configuration and size of the intermediate code. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* sfc: Set net_device::vlan_features appropriatelyBen Hutchings2008-09-031-0/+3

* sfc: Use explicit bool for boolean variables, parameters and return valuesBen Hutchings2008-09-031-25/+22
| | | | | | | | | | | | Replace (cond ? 1 : 0) with cond or !!cond as appropriate, and (cond ? 0 : 1) with !cond. Remove some redundant boolean temporaries. Rename one field that looks like a flag but isn't. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* sfc: Remove inclusion of workarounds.h from efx.cBen Hutchings2008-09-031-1/+0
| | | | | | | efx.c does not use hardware workarounds. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* sfc: Use separate hardware TX queues to select checksum generationBen Hutchings2008-09-031-17/+8
| | | | | | | | | | | | | | | | Checksum generation is an attribute of our hardware TX queues, not TX descriptors. We previously used a single queue and turned checksum generation on or off as requested through ethtool. However, this can result in regenerating checksums in raw packets that should not be modified. We now create 2 hardware TX queues with checksum generation on or off. They are presented to the net core as one queue since it does not know how to select between them. The self-test verifies that a bad checksum is unaltered on the queue with checksum generation off.

* sfc: Replace net_dev->priv with netdev_priv(net_dev)Ben Hutchings2008-09-031-12/+12
| | | | | | | Use of the net_device::priv field is deprecated. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* sfc: Create one RX queue and interrupt per CPU package by defaultBen Hutchings2008-07-221-1/+18
| | | | | | | | | | | Using multiple cores in the same package to handle received traffic does not appear to provide a performance benefit. Therefore use CPU topology information to count CPU packages and use that as the default number of RX queues and interrupts. We rely on interrupt balancing to spread the interrupts across packages.

* sfc: Use a separate workqueue for resetsBen Hutchings2008-07-221-3/+17
| | | | | | | This avoids deadlock in case a reset is triggered during self-test. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* netdev: Do not use TX lock to protect address lists.David S. Miller2008-07-151-4/+2
| | | | | | | | | Now that we have a specific lock to protect the network device unicast and multicast lists, remove extraneous grabs of the TX lock in cases where the code only needs address list protection. Signed-off-by: David S. Miller <davem@davemloft.net>
* netdev: Add netdev->addr_list_lock protection.David S. Miller2008-07-151-0/+2
| | | | | | | | | | | | | Add netif_addr_{lock,unlock}{,_bh}() helpers. Use them to protect operations that operate on or read the network device unicast and multicast address lists. Also use them in cases where the code simply wants to block calls into the driver's ->set_rx_mode() and ->set_multicast_list() methods. Signed-off-by: David S. Miller <davem@davemloft.net>
* sfc: Use kernel I2C system and i2c-algo-bit driverBen Hutchings2008-05-301-0/+2

* sfc: Use resource_size_t for PCI bus addressBen Hutchings2008-05-221-5/+6

* [netdrvr] sfc: Add TSO supportBen Hutchings2008-05-131-1/+3
| | | | | | | | | | The SFC4000 controller does not have hardware support for TSO, and the core GSO code incurs a high cost in allocating and freeing skbs. This TSO implementation uses lightweight packet header structures and is substantially faster. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* New driver "sfc" for Solarstorm SFC4000 controller.Ben Hutchings2008-04-291-0/+2208
The driver supports the 10Xpress PHY and XFP modules on our reference designs SFE4001 and SFE4002 and the SMC models SMC10GPCIe-XFP and SMC10GPCIe-10BT. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
