From 8127d661e77f5ec410093bce411f540afa34593f Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Thu, 29 Aug 2013 19:19:29 +0100 Subject: 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.
