sfc: add sysfs entry to control MCDI tracing

2015-05-27T17:54:51Z

MCDI tracing is enabled per-function with a sysfs file /sys/class/net//device/mcdi_logging Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: add tracing of MCDI commands

2015-05-27T17:54:51Z

MCDI tracing is conditional on CONFIG_SFC_MCDI_LOGGING, which is enabled by default. Each MCDI command will produce a console line like sfc dom:bus:dev:fn ifname: MCDI RPC REQ: xxxxxxxx [yyyyyyyy...] where xxxxxxxx etc. are the raw MCDI payload in 32-bit hex chunks. The response will then produce a similar line with "RESP" instead of "REQ", and containing the MCDI response payload (if any). Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: Minimal support for 40G link speed

2013-09-05T21:32:57Z

Accept and handle 40G link events. Accept ethtool link settings of speed == 40000 && duplex, and set the appropriate MCDI PHY capability. This does not include reporting of 40G media types, as those have not yet been assigned numbers in the MCDI protocol. 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

net: Remove bogus dependencies on INET

2012-11-20T00:13:59Z

Various drivers depend on INET because they used to select INET_LRO, but they have all been converted to use GRO which has no such dependency. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

sfc: Select PTP_1588_CLOCK

2012-11-03T01:30:53Z

This was missed in commit a24006ed12616bde1bbdb26868495906a212d8dc ('ptp: Enable clock drivers along with associated net/PHY drivers') which enabled sfc's clock driver unconditionally. Reported-by: kbuild test robot Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

ptp: Enable clock drivers along with associated net/PHY drivers

2012-11-01T15:35:18Z

Where a PTP clock driver is associated with a net or PHY driver, it should be enabled automatically whenever that driver is enabled. Therefore: - Make PTP clock drivers select rather than depending on PTP_1588_CLOCK - Remove separate boolean options for PTP clock drivers that are built as part of net driver modules. (This also fixes cases where the PTP subsystem is wrongly forced to be built-in.) - Set 'default y' for PTP clock drivers that depend on specific net drivers but are built separately Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

sfc: Add support for IEEE-1588 PTP

2012-09-19T01:54:12Z

Add PTP IEEE-1588 support and make accesible via the PHC subsystem. This work is based on prior code by Andrew Jackson Signed-off-by: Stuart Hodgson [bwh: - Add byte order conversion in efx_ptp_send_times() - Simplify conversion of PPS event times - Add the built-in vs module check to CONFIG_SFC_PTP dependencies] Signed-off-by: Ben Hutchings

sfc: Add SR-IOV back-end support for SFC9000 family

2012-02-16T00:25:13Z

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. This is almost entirely the work of Steve Hodgson, formerly shodgson@solarflare.com. Signed-off-by: Ben Hutchings
