Commit Message

Michal Kubecek March 27, 2020, 12:12 a.m. UTC
Add three string sets related to timestamping information:

  ETH_SS_SOF_TIMESTAMPING: SOF_TIMESTAMPING_* flags
  ETH_SS_TS_TX_TYPES:      timestamping Tx types
  ETH_SS_TS_RX_FILTERS:    timestamping Rx filters

These will be used for TIMESTAMP_GET request.

(kbuild bot omitted netdev list)

Something like below (probably with a better comment text) should get
rid of this warning.
