Thanks, I have two very minor nits below, but otherwise:

Here you're testing if (ret), while in mvneta_txq_init(), in the same
situation, you're doing if (ret < 0). I don't have a preference for one
or the other, but having them consistent between the two lpaces would
be nice.

Spurious change.

Thanks!
