net: hns3: add supports fast reporting of faulty nodes 

driver inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I6QRKC


CVE: NA

----------------------------------------------------------------------

Services are switched only when no response is received within 10 seconds.
As a result, services cannot be switched quickly. Therefore, if the chip
is not suspended, the NIC sends a specific message to notify other nodes
of the event. In this way, the service switchover is performed quickly.
