This series expands XDP TX metadata framework to include ETF HW offload.
Changes since v1:
- rename Time-Based Scheduling (TBS) to Earliest TxTime First (ETF)
- rename launch-time to txtime
I strongly disagree with this renaming (sorry to disagree with Willem).
The i210 and i225 chips call this LaunchTime in their programmers
datasheets, and even in the driver code[1].
Using this "txtime" name in the code is also confusing, because how can
people reading the code know the difference between:
- tmo_request_timestamp and tmo_request_txtime
