From: Willem de Bruijn <[email protected]>
Enable safe hardware pacing offload on a first device (idpf), plus support.
- Add rtnetlink support for admin control over the device feature
- Add device support to the idpf driver
Besides the main feature, also
- Small optimization to FQ offload: avoid unnecessary ktime_.._get().
- Expand so_txtime drv-net test with hw offload testcases.
- Expand pktgen with txtime feature.
Details and detailed changelog in the individual patches.
High level changes:
v3 -> v4
- Replace ethtool API with rtnetlink
- Drop/defer pktgen patch: not essential
NOTE: the idpf patch will have a minor merge conflict with commit
"idpf: add missing cpu_to_le32 in idpf_tx_splitq_build_flow_desc"
(https://lore.kernel.org/netdev/[email protected]/).
I expect that this series will need another revision, at which point
that fix will have made its way to net-next. There is also a fix to
so_txtime.py outstanding, but that is structured so that these do not
conflict.
