net/mlx5e: ethtool, Add support for EEPROM high pages query

2019-05-01T21:39:16Z

Add the support to read additional EEPROM information from high pages. Information for modules such as SFF-8436 and SFF-8636: 1) Application select table 2) User writable EEPROM 3) Thresholds and alarms Signed-off-by: Erez Alfasi Signed-off-by: Saeed Mahameed

net/mlx5e: Fix GRE key by controlling port tunnel entropy calculation

2019-02-22T21:38:23Z

Flow entropy is calculated on the inner packet headers and used for flow distribution in processing, routing etc. For GRE-type encapsulations the entropy value is placed in the eight LSB of the key field in the GRE header as defined in NVGRE RFC 7637. For UDP based encapsulations the entropy value is placed in the source port of the UDP header. The hardware may support entropy calculation specifically for GRE and for all tunneling protocols. With commit df2ef3bff193 ("net/mlx5e: Add GRE protocol offloading") GRE is offloaded, but the hardware is configured by default to calculate flow entropy so packets transmitted on the wire have a wrong key. To support UDP based tunnels (i.e VXLAN), GRE (i.e. no flow entropy) and NVGRE (i.e. with flow entropy) the hardware behaviour must be controlled by the driver. Ensure port entropy calculation is enabled for offloaded VXLAN tunnels and disable port entropy calculation in the presence of offloaded GRE tunnels by monitoring the presence of entropy enabling tunnels (i.e VXLAN) and entropy disabing tunnels (i.e GRE).

net/mlx5: Add support to ext_* fields introduced in Port Type and Speed register

2019-02-14T20:14:42Z

This patch exposes new link modes (including 50Gbps per lane), and ext_* fields which describes the new link modes in Port Type and Speed register (PTYS). Access functions, translation functions (speed <-> HW bits) and link max speed function were modified. Signed-off-by: Aya Levin Reviewed-by: Eran Ben Elisha Signed-off-by: Saeed Mahameed

net/mlx5: Refactor queries to speed fields in Port Type and Speed register

2019-02-14T20:14:42Z

This patch fascicles queries to speed related fields in Port Type and Speed register (PTYS) into a single API. I addition, this patch refactors functions which serves only Ethernet driver: remove the protocol type as an input parameter, move code from 'core' directory into 'en' directory and add 'eth' prefix to the function's name. The patch also encapsulates functions that are not used outside the Ethernet driver removes redundant include files.

net/mlx5: Device events, Use async events chain

2018-11-26T21:39:34Z

Move all the generic async events handling into new specific events handling file events.c to keep eq.c file clean from concrete event logic handling. Use new API to register for NOTIFY_ANY to handle generic events and dispatch allowed events to mlx5_core consumers (mlx5_ib and mlx5e) Signed-off-by: Saeed Mahameed

net/mlx5e: PFC stall prevention support

2018-03-26T20:46:46Z

Implement set/get functions to configure PFC stall prevention timeout by tunables api through ethtool. By default the stall prevention timeout is configured to 8 sec. Timeout range is: 80-8000 msec. Enabling stall prevention with the auto timeout will set the timeout to 100 msec. Signed-off-by: Inbar Karmy Signed-off-by: Saeed Mahameed

net/mlx5: QPTS and QPDPM register firmware command support

2017-11-05T04:26:21Z

The QPTS register allows changing the priority trust state between pcp and dscp. Add support to get/set trust state from device. When the port is in pcp/dscp trust state, packet is routed by hardware to matching priority based on its pcp/dscp value respectively. The QPDPM register allow channing the dscp to priority mapping. Add support to get/set dscp to priority mapping from device. Note that to change a dscp mapping, the "e" bit of this dscp structure must be set in the QPDPM firmware command.

net/mlx5e: DCBNL, Implement tc with ets type and zero bandwidth

2017-10-26T07:47:27Z

Previously, tc with ets type and zero bandwidth is not accepted by driver. This behavior does not follow the IEEE802.1qaz spec. If there are tcs with ets type and zero bandwidth, these tcs are assigned to the lowest priority tc_group #0. We equally distribute 100% bw of the tc_group #0 to these zero bandwidth ets tcs. Also, the non zero bandwidth ets tcs are assigned to tc_group #1. If there is no zero bandwidth ets tc, the non zero bandwidth ets tcs are assigned to tc_group #0.
