[PATCH net-next 11/12] net: hns3: stop sending keep alive msg to PF when VF is resetting

[Huazhong Tan]

From: Jian Shen <shenjia...@huawei.com>

When VF is resetting, it can't communicate to PF with mailbox msg.
This patch adds reset state checking before sending keep alive msg
to PF.

Fixes: a6d818e31d08 ("net: hns3: Add vport alive state checking support")
