Subject: [PATCH net-next 10/11] net: hns3: Remove redundant codes of query advertised flow control abilitiy

From: Jian Shen <shenjian15@...wei.com>

If the advertised flow control ability has been fetched using
phy_ethtool_ksettings_get() or hclge_get_link_mode() then it is
unnecessary to fetch them again later using hclge_get_flowctrl_adv().
This patch removes it.
