From afd4aea03f597f29421dc5767e7d1f754730ec23 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Sun, 29 Nov 2009 15:15:25 +0000 Subject: sfc: Add support for SFC9000 family (1) This adds support for the SFC9000 family of 10G Ethernet controllers and LAN-on-motherboard chips, starting with the SFL9021 'Siena' and SFC9020 'Bethpage'. The SFC9000 family is based on the SFC4000 'Falcon' architecture, but with some significant changes: - Two ports are associated with two independent PCI functions (except SFC9010) - Integrated 10GBASE-T PHY(s) (SFL9021/9022) - MAC, PHY and board peripherals are managed by firmware - Driver does not require board-specific code - Firmware supports wake-on-LAN and lights-out management through NC-SI - IPv6 checksum offload and RSS - Filtering by MAC address and VLAN (not included in this code) - PCI SR-IOV (not included in this code) Credit for this code is largely due to my colleagues at Solarflare: Guido Barzini Steve Hodgson Kieran Mansley Matthew Slattery Neil Turton Signed-off-by: Ben Hutchings Signed-off-by: David S.
