2012-01-27sfc: Remove efx_nic_type::push_multicast_hash operationBen Hutchings1-4/+1
Both implementations of efx_nic_type::reconfigure_mac operation push the multicast hash filter to the hardware. It is therefore redundant to call efx_nic_type::push_multicast_hash as well. efx_mcdi_mac_reconfigure() also uses this operation, but the implementation for Siena just uses MCDI anyway. Merge that into efx_mcdi_mac_reconfigure(). Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-01-27sfc: Merge efx_mac_operations into efx_nic_typeBen Hutchings1-11/+6
No NICs need to switch efx_mac_operations at run-time, and the MAC operations are fairly closely bound to NIC types. Move efx_mac_operations::reconfigure to efx_nic_type::reconfigure_mac and efx_mac_operations::check_fault fo efx_nic_type::check_mac_fault. Change callers to call through efx->type or directly if the NIC type is known. Remove efx_mac_operations::update_stats. The implementations for Falcon used to fetch MAC statistics synchronously and this was used by efx_register_netdev() to clear statistics after running self-tests. However, it now only converts statistics that have already been fetched (and that only for Falcon), and the call from efx_register_netdev() has no effect.

2012-01-27sfc: Hold efx_nic::stats_lock while reading efx_nic::mac_statsBen Hutchings1-1/+3
efx_nic::stats_lock is used to serialise stats updates, but each reader was dropping it before it finished reading efx_nic::mac_stats. If there were concurrent stats reads using procfs, or one using procfs and one using ethtool, an update could race with a read. On a 32-bit system, the reader could see word-tearing of 64-bit stats (32 bits of the old value and 32 bits of the new). Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-01-27sfc: Remove fallback for invalid permanent MAC addressBen Hutchings1-30/+2
By the time we look at the MAC address in efx_probe_port(), either the driver or the firmware has already validated the board configuration. The possibility of having an invalid MAC address just isn't worth considering. It certainly isn't worth having a compile-time option for this. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-01-09sfc: Set default parallelism to per-core by defaultBen Hutchings1-7/+7
The previous default of per-package can be more CPU-efficient, but users generally seem to prefer per-core. It should also allow accelerated RFS to direct packets more precisely, if IRQ affinity is properly spread out. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-01-09sfc: Rename efx_wanted_channels() to efx_wanted_parallelism()Ben Hutchings1-4/+2
This function returns the degree of parallelism wanted, which is not necessarily the total number of channels we want to create. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2011-12-16ethtool: Define and apply a default policy for RX flow hash indirectionBen Hutchings1-1/+2
All drivers that support modification of the RX flow hash indirection table initialise it in the same way: RX rings are assigned to table entries in rotation. Make that default policy explicit by having them call a ethtool_rxfh_indir_default() function. In the ethtool core, add support for a zero size value for ETHTOOL_SRXFHINDIR, which resets the table to this default.

2011-09-17sfc: Correct reporting and validation of TX interrupt coalescingBen Hutchings1-0/+18
The reported TX IRQ moderation is generated in a completely crazy way. Make it simple and correct. When channels are shared between RX and TX, TX IRQ moderation must be the same as RX IRQ moderation, but must be specified as 0! Allow it to be either specified as the same, or left at its previous value in which case it will be quietly overridden.
