Checks
Commit Message
From: "Wei Hu (Xavier)" <xavier.huwei@huawei.com>
This patch extact checking rx_queue_id or tx_queue_id into two separate
common functions named eth_dev_validate_rx_queue and
eth_dev_validate_tx_queue.

v4 -> v5:
1. remove inline.
2. add 'const' to dev to highlight that it changes nothing.
3. RX -> Rx, TX -> Tx.
4. log port ID in the error branch.
5. 'if (ret)' -> 'if (ret != 0)'
6. split the original patch into three separate patches.
v3 -> v4:
1. dropping the 'rte_' prefix from the funcitons names.
2. get "struct rte_eth_dev *dev" as parameter and drop the port_id
validation in the function named eth_dev_validate_rx_queue and
eth_dev_validate_tx_queue.
3. replace "setupped" with "setup" in the commit log and titile.
v2 -> v3:
don't break lines in format strings.
v1 -> v2:
1. replace %"PRIu16" with %u.
2. extact two common functions which validate RXQ/TXQ ids and
whether it has been set up or not.
