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 <bhutchings@solarflare.com> Signed-off-by: David S.

sfc: Add hwmon driver for boards using SFC9000-family controllers The SFC9000-family controllers have firmware to manage all board peripherals including temperature, heat sink continuity and voltage sensors. The firmware reports sensor alarms, which we log, and will shut down the board if necessary. Some users may want to monitor their boards more closely, so add an hwmon driver that exposes all sensors reported by the firmware. Move efx_mcdi_sensor_event() into the new file so it can share the array of sensor labels with the hwmon driver. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

sfc: Add SR-IOV back-end support for SFC9000 family On the SFC9000 family, each port has 1024 Virtual Interfaces (VIs), each with an RX queue, a TX queue, an event queue and a mailbox register. These may be assigned to up to 127 SR-IOV virtual functions per port, with up to 64 VIs per VF. We allocate an extra channel (IRQ and event queue only) to receive requests from VF drivers. There is a per-port limit of 4 concurrent RX queue flushes, and queue flushes may be initiated by the MC in response to a Function Level Reset (FLR) of a VF. Therefore, when SR-IOV is in use, we submit all flush requests via the MC. The RSS indirection table is shared with VFs, so the number of RX queues used in the PF is limited to the number of VIs per VF.

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.
