* sfxge(4): report support for Tx checksum op descriptorsAndrew Rybchenko2018-12-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | FreeBSD driver needs a patch to provide a means for packets which do not need checksum offload but have flow ID set to avoid hitting only the first Tx queue (which has been used for packets not needing checksum offload). This should be possible on Huntington, Medford or Medford2 chips since these support toggling checksum offload on any given queue dynamically by means of pushing option descriptors. The patch for FreeBSD driver will then need a means to figure out whether the feature can be used, and testing adapter family might not be a good solution. This patch adds a feature bit specifically to indicate support for checksum option descriptors. The new feature bits may have more users in future, apart from the mentioned FreeBSD patch.

| | | | | | | | | | | | | | | | Add a function which makes an MCDI GET_LINK request and packages up the results. Currently, the get-link function is triggered from several entry points which then pass on or store selected parts of the data. When the driver needs to obtain the current link state, it is more efficient to do this in a single call.

* sfxge(4): add information if TSO workaround is requiredAndrew Rybchenko2018-11-301-0/+1
| | | | | | | | | | | | | | | | | | | In SF bug 61297 it's been confirmed that the hardware does not always calculate the TCP checksum correctly with TSO sends. The value of the Total Length field (IPv4) or Payload Length field (IPv6) is the critical factor. We're sufficiently confident that if these fields are zero then the checksum will be calculated correctly. The information may be used by the drivers to check if the workaround is required when FATSOv2 is implemented.

| | | | | | | | | | | | | | | Equal stride super-buffer Rx mode is supported by DPDK firmware variant. One Rx descriptor provides many Rx buffers to firmware. Rx buffers follow each other with specified stride. Also it supports head of line blocking with timeout to address drops when no Rx descriptors are available. So it gives extra time to the driver to provide Rx descriptors before drop. Sponsored by: Solarflare Communications, Inc.

* sfxge(4): honour packed stream RSS restrictionAndrew Rybchenko2018-11-291-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Packed stream firmware variant on EF10 adapters has a number of properties which must be taken into account: - Only one exclusive RSS context is available per port. - Only IP addresses can contribute to the hash value. Huntington and Medford have one more limitation which is important for the drivers capable of packed stream: - Hash algorithm is non-standard (i.e. non-Toeplitz). This implies XORing together source + destination IP addresses (or last four bytes in the case of IPv6) and using the result as the input to a Toeplitz hash. This patch provides a number of improvements in order to treat the mentioned limitations in the common code. If the firmware variant is packed stream, the list of supported hash tuples will include less variants, and the maximum number of RSS contexts will be set to one.

| | | | | | | | | | | | | | | | | | | | | Add filter match flag to distinguish filters applied only to encapsulated packets. Match flags set should allow to determine whether a filter is supported or not. The problem is that if specification has supported set outer match flags and specified encapsulation without any inner flags, check says that it is supported, and filter insertion is performed. However, there is no filtering of the encapsulated traffic. A new flag is added to solve this problem and separate the filters for the encapsulated packets.
