Subject: [PATCH V1 net-next 1/5] net: ena: change num_queues to num_io_queues for clarity and consistency
From: Sameeh Jubran <sameehj@...zon.com>
Most places in the code refer to the IO queues as io_queues and not
simply queues. Examples - max_io_queues_per_vf, ENA_MAX_NUM_IO_QUEUES,
ena_destroy_all_io_queues() etc..
We are also adding the new max_num_io_queues field to struct ena_adapter
in the following commit.
The changes included in this commit are:
struct ena_adapter->num_queues => struct ena_adapter->num_io_queues
