sfc: separate out SFC4000 ("Falcon") support into new sfc-falcon driver

2016-11-30T15:16:58Z

Rationale: The differences between Falcon and Siena are in many ways larger than those between Siena and EF10 (despite Siena being nominally "Falcon- architecture"); for instance, Falcon has no MCPU, so there is no MCDI. Removing Falcon support from the sfc driver should simplify the latter, and avoid the possibility of Falcon support being broken by changes to sfc (which are rarely if ever tested on Falcon, it being end-of-lifed hardware). The sfc-falcon driver created in this changeset is essentially a copy of the sfc driver, but with Siena- and EF10-specific code, including MCDI, removed and with the "efx_" identifier prefix changed to "ef4_" (for "EFX 4000- series") to avoid collisions when both drivers are built-in. This changeset removes Falcon from the sfc driver's PCI ID table; then in sfc I've removed obvious Falcon-related code: I removed the Falcon NIC functions, Falcon PHY code, and EFX_REV_FALCON_*, then fixed up everything that referenced them. Also, increment minor version of both drivers (to 4.1). For now, CONFIG_SFC selects CONFIG_SFC_FALCON, so that updating old configs doesn't cause Falcon support to disappear; but that should be undone at some point in the future.

sfc: set interrupt moderation via MCDI

2016-08-13T03:42:20Z

SFN8000-series NICs require a new method of setting interrupt moderation, via MCDI. This is indicated by a workaround flag. This new MCDI command takes an explicit time value rather than a number of ticks. It therefore makes sense to also store the moderation values in terms of time, since that is what the ethtool interface is interested in. Signed-off-by: Bert Kenward Signed-off-by: David S. Miller

sfc: Update copyright banners

Update the dates for files that have been added to in 2012-2013. Drop the 'Solarstorm' brand name that's still lingering here. Signed-off-by: Ben Hutchings

sfc: Add support for Solarflare SFC9100 family

2013-08-29T18:19:29Z

This adds support for the EF10 network controller architecture and the SFC9100 family, starting with SFC9120 'Farmingdale', and bumps the driver version to 4.0. New features in the SFC9100 family include: - Flexible allocation of internal resources to PCIe physical and virtual functions under firmware control - RX event merging to reduce DMA writes at high packet rates - Integrated RX timestamping - PIO buffers for lower TX latency - Firmware-driven data path that supports additional offload features and filter types - Delivery of packets between functions and to multiple recipients, allowing firmware to implement a vswitch - Multiple RX flow hash (RSS) contexts with their own hash keys and indirection tables - 40G MAC (single port only) ...not all of which are enabled in this initial driver or the initial firmware release. Much of the new code is by Jon Cooper. Signed-off-by: Ben Hutchings

sfc: EFX_WORKAROUND_ALWAYS is really specific to Falcon-architecture

2013-08-21T19:20:43Z

The workarounds that currently use EFX_WORKAROUND_ALWAYS are in Falcon-specific or Falcon-arch-specific code, so get rid of the conditions altogether. Add/move comments as appropriate. Signed-off-by: Ben Hutchings
