[dpdk-dev] [PATCH v3 1/9] net/hns3: support Rx interrupt

[Wei Hu (Xavier)]

From: Hao Chen <chenhao164@huawei.com>

This patch adds supports of receive packets through interrupt mode for hns3
PF/VF driver. The following ops functions should be implemented defined in
the struct eth_dev_ops:
rx_queue_intr_enable
rx_queue_intr_disable

Signed-off-by: Hao Chen <chenhao164@huawei.com>
Signed-off-by: Wei Hu (Xavier) <xavier.huwei@huawei.com>
---
v2 -> v3:
	1.Remove the irrelevant '.rx_queue_count' ops implementation
	  function from this patch.
v1 -> v2:
	1.No change.

[dpdk-dev] [PATCH v3 2/9] net/hns3: get link state change through mailbox

[Wei Hu (Xavier)]

From: Hongbo Zheng <zhenghongbo3@huawei.com>

Currently, firmware adds the function of sending message to PF driver
through mailbox when the link status is changed, hns3 PMD driver can
usually recognize link state change faster through the message.

And in some extreme cases, this way is not faster than existing method
regularly updating link status by issing the command every second in PF
driver, because of the parallel processing of mailbox and command messages
in firmware. So we reserve updating link status using timers in PF driver,
and add querying link status by issuing command to the firmware in
'.link_update' ops implementation function named hns3_dev_link_update to
solve the out of date link status.
