From 32e6d104c6fe01713a039a98842e4d2f6bb505ec Mon Sep 17 00:00:00 2001 From: Jian Shen Date: Mon, 31 May 2021 10:38:43 +0800 Subject: net: hns3: add query basic info support for VF There are some features of VF depend on PF, so it's necessary for VF to know whether PF supports. For compatibility, modify the mailbox HCLGE_MBX_GET_TCINFO, extend its function, use to get the basic information of PF, including mailbox api version and PF capabilities.
