net/hns3: support multiple process This patch adds multiple process support for hns3 PMD driver. Multi-process support selection queue by configuring RSS or flow director. The primary process supports various management ops, and the secondary process only supports queries ops. The primary process notifies the secondary processes to start or stop tranceiver.

net/hns3: check multi-process action register result Currently, there is a coverity defect warning about hns3 PMD driver, the detail information as blow: CID 289969 (#1 of 1): Unchecked return value (CHECKED_RETURN) 1. check_return: Calling rte_mp_action_register without checking return value (as is done elsewhere 11 out of 13 times). The problem is that missing checking the return value of calling the API rte_mp_action_register during initialization. If registering an action function for primary and secondary communication failed, the secondary process can't work properly. This patch fixes it by adding check return value of the API function named rte_mp_action_register in the '.dev_init' implementation function of hns3 PMD driver.
