2024-04-06ethtool: add interface to read Tx hardware timestamping statisticsRahul Rameshbabu1-0/+17
Multiple network devices that support hardware timestamping appear to have common behavior with regards to timestamp handling. Implement common Tx hardware timestamping statistics in a tx_stats struct_group. Common Rx hardware timestamping statistics can subsequently be implemented in a rx_stats struct_group for ethtool_ts_stats.

When interfacing with the ethtool commands it's handy to be able to use the names of the flags. Example: ethnl.pause_get({"header": {"dev-index": cfg.ifindex, "flags": {'stats'}}}) Note that not all commands accept all the flags, but the meaning of the bits does not change command to command.

2023-12-14net: ethtool: add support for symmetric-xor RSS hashAhmed Zaki1-0/+4
Symmetric RSS hash functions are beneficial in applications that monitor both Tx and Rx packets of the same flow (IDS, software firewalls, ..etc). Getting all traffic of the same flow on the same RX queue results in higher CPU cache efficiency. A NIC that supports "symmetric-xor" can achieve this RSS hash symmetry by XORing the source and destination fields and pass the values to the RSS hash algorithm. The user may request RSS hash symmetry for a specific algorithm, via: # ethtool -X eth0 hfunc <hash_alg> symmetric-xor or turn symmetry off (asymmetric) by: # ethtool -X eth0 hfunc <hash_alg> The specific fields for each flow type should then be specified as usual via: # ethtool -N|-U eth0 rx-flow-hash <flow_type> s|d|f|n Reviewed-by: Wojciech Drewek <wojciech.drewek@intel.com> Signed-off-by: Ahmed Zaki <ahmed.zaki@intel.com> Link: https://lore.kernel.org/r/20231213003321.605376-4-ahmed.zaki@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

I relicensed Netlink spec code to GPL-2.0 OR BSD-3-Clause but we still put a slightly different license on the uAPI header than the rest of the code. Use the Linux-syscall-note on all the specs and all generated code. It's moot for kernel code, but should not hurt. This way the licenses match everywhere.

I was intending to make all the Netlink Spec code BSD-3-Clause to ease the adoption but it appears that: - I fumbled the uAPI and used "GPL WITH uAPI note" there - it gives people pause as they expect GPL in the kernel As suggested by Chuck re-license under dual. This gives us benefit of full BSD freedom while fulfilling the broad "kernel is under GPL" expectations.
