[PATCH 01/25] net: hns3: merge mac state HCLGE_MAC_TO_DEL and HCLGE_MAC_DEL_FAIL
by Yang Yingliang 26 Apr '20

26 Apr '20

From: shenhao <shenhao21(a)huawei.com> driver inclusion category: bugfix bugzilla: NA CVE: NA -------------------------------------------- HCLGE_MAC_DEL_FAIL is a middle state for mac address handling, it can be merged with HCLGE_MAC_TO_DEL. Btw, this patch also change the enum name from HCLGE_MAC_ADDR_STATE to HCLGE_MAC_NODE_STATE, for it's used to indicate the state of mac node.

We found out that after phy up, the hardware report another oob interrupt, but did not follow a phy up interrupt. like: oob ready -> phy up -> DEV found -> oob read -> wait phy up -> timeout We run link reset when wait phy up timeout, and it make a normal disk into reset processing. So we made some circumvention action in the code, so that this abnormal oob interrupt will not start the timer to wait for phy up.

[PATCH] net: hns3: add suspend/resume function for hns3 driver
by Jian Shen 21 Apr '20

21 Apr '20

From: Hao Shen <shenhao21(a)huawei.com> The suspend and resume feature is useful when you want to save the current state of your machine, and continue work later from the same state.
