2011-02-28sfc: Read MC firmware version when requested through ethtoolBen Hutchings
We currently make no use of siena_nic_data::fw_{version,build} except to format the firmware version for ethtool_get_drvinfo(). Since we only read the version at start of day, this information is incorrect after an MC firmware update. Remove the cached version information and read it via MCDI whenever it is requested.

2011-02-15sfc: Distinguish queue lookup from test for queue existenceBen Hutchings
efx_channel_get_{rx,tx}_queue() currently return NULL if the channel isn't used for traffic in that direction. In most cases this is a bug, but some callers rely on it as an existence test. Add existence test functions efx_channel_has_{rx_queue,tx_queues}() and use them as appropriate. Change efx_channel_get_{rx,tx}_queue() to assert that the requested queue exists. Remove now-redundant initialisation from efx_set_channels(). Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2010-12-10netdev: Use default implementation of ethtool_ops::get_link where possibleBen Hutchings
Various drivers are using implementations of ethtool_ops::get_link that are equivalent to the default ethtool_op_get_link(). Change them to use that instead. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-12-07sfc: Generalise filter spec initialisationBen Hutchings
Move search_depth arrays into per-table state. Define initialisation function efx_filter_init_rx() which sets everything apart from the match fields. Define efx_filter_set_{ipv4_local,ipv4_full,eth_local}() to set the match fields. This allows some simplification of callers and later support for additional protocols and more flexible matching using multiple calls to these functions.

2010-12-07sfc: Remove filter table IDs from filter functionsBen Hutchings
The separation between filter tables is largely an internal detail and it may be removed in future hardware. To prepare for that: - Merge table ID with filter index to make an opaque filter ID - Wrap efx_filter_table_clear() with a function that clears filters from both RX tables, which is all that the current caller requires Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2010-12-07sfc: Log start and end of ethtool self-test at INFO levelBen Hutchings

2010-09-10sfc: Allow changing the DMA ring sizes dynamically via ethtoolBen Hutchings

2010-09-10sfc: Refactor channel and queue lookup and iterationBen Hutchings
In preparation for changes to the way channels and queue structures are allocated, revise the macros and functions used to look up and iterator over them. - Replace efx_for_each_tx_queue() with iteration over channels then TX queues - Replace efx_for_each_rx_queue() with iteration over channels then RX queues (with one exception, shortly to be removed) - Introduce efx_get_{channel,rx_queue,tx_queue}() functions to look up channels and queues by index - Introduce efx_channel_get_{rx,tx}_queue() functions to look up a channel's queues Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-07-07net: fix 64 bit counters on 32 bit archesEric Dumazet
There is a small possibility that a reader gets incorrect values on 32 bit arches. SNMP applications could catch incorrect counters when a 32bit high part is changed by another stats consumer/provider. One way to solve this is to add a rtnl_link_stats64 param to all ndo_get_stats64() methods, and also add such a parameter to dev_get_stats(). Rule is that we are not allowed to use dev->stats64 as a temporary storage for 64bit stats, but a caller provided area (usually on stack) Old drivers (only providing get_stats() method) need no changes.

2010-06-30sfc: Add support for RX flow hash controlBen Hutchings

2010-06-30ethtool: Change ethtool_op_set_flags to validate flagsBen Hutchings
ethtool_op_set_flags() does not check for unsupported flags, and has no way of doing so. This means it is not suitable for use as a default implementation of ethtool_ops::set_flags. Add a 'supported' parameter specifying the flags that the driver and hardware support, validate the requested flags against this, and change all current callers to pass this parameter. Change some other trivial implementations of ethtool_ops::set_flags to call ethtool_op_set_flags().

2010-04-28sfc: Create multiple TX queuesBen Hutchings

2010-02-04sfc: Replace PHY MDIO test with an 'alive' testBen Hutchings
SFC9000-family boards do not all use MDIO PHYs, so we need a different test for PHY aliveness. Introduce a PHY operation test_alive(). For PHYs attached to Falcon, use a common implementation based on the existing PHY MDIO test. For PHYs managed through MCDI, use the appropriate MCDI request. Change test name in ethtool from 'core mdio' to 'phy alive'. Rename test_results::mdio to phy_alive and test_results::phy to phy_ext.

2009-11-30sfc: Refactor link configurationBen Hutchings
Refactor PHY, MAC and NIC configuration operations so that the existing link configuration can be re-pushed with: efx->phy_op->reconfigure(efx); efx->mac_op->reconfigure(efx); and a new configuration with: efx->nic_op->reconfigure_port(efx); (plus locking and error-checking). We have not held the link settings in software (aside from flow control), and have relied on asking the hardware what they are. This is a problem because in some cases the hardware may no longer be in a state to tell us. In particular, if an entire multi-port board is reset through one port, the driver bindings to other ports have no chance to save settings before recovering. We only actually need to keep track of the autonegotiation settings, so add an ethtool advertising mask to struct efx_nic, initialise it in PHY init and update it as necessary. Remove now-unneeded uses of efx_phy_op::{get,set}_settings() and struct ethtool_cmd. Much of this was done by Steve Hodgson <shodgson@solarflare.com>.
