Add the support to read additional EEPROM information from high pages.

2019-04-19net/mlx5e: ethtool, Remove unsupported SFP EEPROM high pages queryErez Alfasi1-4/+0
Querying EEPROM high pages data for SFP module is currently not supported by our driver and yet queried, resulting in invalid FW queries. Set the EEPROM ethtool data length to 256 for SFP module will limit the reading for page 0 only and prevent invalid FW queries.

2019-02-22net/mlx5e: Fix GRE key by controlling port tunnel entropy calculationEli Britstein1-3/+2
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).

2019-02-22net/mlx5: Use read-modify-write when changing PCMR register valuesEli Britstein1-0/+4
Currently changing a PCMR field is done by setting the field in a zeroed buffer, zeroing other unrelated fields. Fix this behaviour by modifying only the required field after first reading the current register values, as a pre-step towards using more fields in PCMR register.

2019-02-14net/mlx5: Refactor queries to speed fields in Port Type and Speed registerAya Levin1-106/+0
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.

The muxing can be done using a BPF program which hashes the incoming packet. From Craig Gallek. 5) Add a multiplexer for TCP streams, to provide a messaged based interface. BPF programs can be used to determine the message boundaries. From Tom Herbert. 6) Add 802.1AE MACSEC support, from Sabrina Dubroca. 7) Avoid factorial complexity when taking down an inetdev interface with lots of configured addresses. We were doing things like traversing the entire address less for each address removed, and flushing the entire netfilter conntrack table for every address as well. 8) Add and use SKB bulk free infrastructure, from Jesper Brouer. 9) Allow offloading u32 classifiers to hardware, and implement for ixgbe, from John Fastabend. 10) Allow configuring IRQ coalescing parameters on a per-queue basis, from Kan Liang. 11) Extend ethtool so that larger link mode masks can be supported. From David Decotigny. 12) Introduce devlink, which can be used to configure port link types (ethernet vs Infiniband, etc.), port splitting, and switch device level attributes as a whole. From Jiri Pirko. 13) Hardware offload support for flower classifiers, from Amir Vadai. 14) Add "Local Checksum Offload". Basically, for a tunneled packet the checksum of the outer header is 'constant' (because with the checksum field filled into the inner protocol header, the payload of the outer frame checksums to 'zero'), and we can take advantage of that in various ways.
