The process of function hclge_add_fd_entry() is complex and prolix. To make it more readable, extract the process of fs->ring_cookie to a single function.

Currently, there are too many branches for hclge_fd_convert_tuple(). And it may be more when add new tuples. Refactor it by sorting the tuples according to their length. So it only needs several KEY_OPT now, and being flexible to add new tuples.

From: Jian Shen shenjian15@huawei.com

Currently, there are 3 flow director work modes in HNS3 driver, include EP(ethtool), tc flower and aRFS. The flow director rules are configured synchronously and need holding spin lock. With this limitation, all the commands with firmware are also needed to use spin lock.

To eliminate the limitation, configure flow director rules asynchronously. The rules are still kept in the fd_rule_list with below states. TO_ADD: the rule is waiting to add to hardware TO_DEL: the rule is waiting to remove from hardware ADDING: the rule is adding to hardware ACTIVE: the rule is already added in hardware

When receive a new request to add or delete flow director rule, check whether the rule location is existent, update the rule content and state, and request to schedule the service task to finish the configuration.

For only PF driver can configure flow director rule, it's better to call hclge_del_all_fd_entries() directly in hclge layer, rather than call hns3_del_all_fd_entries() in hns3 layer. Then the ae_algo->ops.del_all_fd_entries can be removed.

From: Jian Shen shenjian15@huawei.com

For device version V3, it supports queue bonding, which can identify the tuple information of TCP stream, and create flow director rules automatically, in order to keep the tx and rx packets are in the same queue pair. The driver set FD_ADD field of TX BD for TCP SYN packet, and set FD_DEL filed for TCP FIN or RST packet. The hardware create or remove a fd rule according to the TX BD, and it also support to age-out a rule if not hit for a long time.

The queue bonding mode is default to be disabled, and can be enabled/disabled with ethtool priv-flags command.
