Not so much critical to me but the entry has a field having repeating name.
	priv->drop_hrxq.hrxq and priv->drop_hrxq.rxq
Sounds still confusing...

However, the assumption is there's only one drop queue while the regular ones
have multiple instances.

Yes, that's what I'm telling you. *_{new,get,release}() accesses priv, then why
the pointer (which is saved in priv) is needed as an argument?

> This is also to keep a consistency between regular hrxqs, and drop hrxq also.
Not sure why that consistency has to be kept.

int mlx5_rxq_release(struct rte_eth_dev *dev, uint16_t idx);
int mlx5_hrxq_release(struct rte_eth_dev *dev, struct mlx5_hrxq *hxrq);

mlx5_rxq_release() takes index as the instances are stored in an array and
mlx5_hrxq_release() takes pointer as the instances are stored in a list.

Then, what if there's only one instance and no need to search?
Not taking such an argument sounds more consistent...

Thanks,
Yongseok
