[dpdk-dev] [PATCH 0/3] remove dependence on Tx queue flags

[Qi Zhang]

The patchset remove txq_flags dependence on Intel devices: ixgbe, e1000, fm10k.
(i40e has been covered on another fix patchset)

Qi Zhang (3):
  net/ixgbe: remove dependence on Tx queue flags

[dpdk-dev] [PATCH 1/3] net/ixgbe: remove dependence on Tx queue flags

[Qi Zhang]

Since we move to new offload APIs, txq_flags is no long needed.
This patch remove the dependence on that.

Fixes: 51215925a32f ("net/ixgbe: convert to new Tx offloads API")

But old apps still use txq_flags returned by dev_info_get.
Removing it right now will mean this value will be undefined.

Same here - old apps can still use it.
Ideally we'll have to fill it based on txq->offloads value.

My understanding is PMD should not be aware of txq_flags anymore.
and ethdev layer is the place to responsible for the conversion if we think it still necessary to support txq_flags for old applicaiton

But I got your point, there is something missing if we only have the PMD patch, so I'd like to hold this until ethdev layer is ready and I think this will not block
https://dpdk.org/ml/archives/dev/2018-May/099864.html since txq_flags is not be involved to any decision already.

[dpdk-dev] [PATCH 2/3] net/e1000: remove dependence on Tx queue flags

[Qi Zhang]

Since we move to new offload APIs, txq_flags is no long needed.
This patch remove the dependence on that.

Fixes: e5c05e6590ea ("net/e1000: convert to new Tx offloads API")

Just worth to mention that:
