sfc: Add support for Solarflare SFC9100 family 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 <bhutchings@solarflare.com>

sfc: set interrupt moderation via MCDI 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.
