Re: [PATCH] net/mlx5: fix init on secondary process

[Adrien Mazarguil <adrien.mazarguil@6wind.com>]

Hi Olivier,

Secondary process support's got overlooked during this refactoring, thanks
for the patch. However can you describe the issue you're addressing as part
of the commit log?

I think problems started when txq got mistakenly converted to
primary_txq_ctrl in 21c8bb4928c9 ("net/mlx5: split Tx queue structure"), you
may add a Fixes line for that one as well.

Otherwise, this patch looks fine to me.
