In some cases, it seems that the txq mbuf vector release mode
is enabled first, and then it is confirmed that the conditions
for using the vector mode are not met.

This patch puts the txq vector mode startup process after the
condition detection.

Fixes: 28f9002ab67f ("net/ice: add Tx AVX512 offload path")

Hi Alvin,

As far as I understand the impact is failure in the Tx vector patch selection,
can you please update the patch title to reflect it?

Also can you please describe a little more what is "txq mbuf vector release
mode" and what is the root cause for it to be enabled first?

What is "txq vector mode startup process"?

Hi Ferruh,

Thanks for your advice. I'll update the commit log in V2.
If the following changes are appropriate?

net/ice: fix txq vector path selection

If Tx vector mode is disabled, the txq vector mode should be disabled too.
This patch adds checking of Tx vector mode before enabling txq vector mode.

If vector mode is not allowed for Tx, no need to perform vector related setup for Tx queue

> 
> This patch adds checking of Tx vector mode before enabling txq vector mode.

The patch deferred vector setup for Tx queue to the place that vector mode is confirmed to be allowed.

No need to add Cc stable, if you fix on current release.
