Miller" <davem@...emloft.net>, Jakub Kicinski <kuba@...nel.org>, Huazhong Tan <tanhuazhong@...wei.com>, Jian Shen <shenjian15@...wei.com>, netdev@...r.kernel.org Cc: kernel-janitors@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH][next] net: hns3: fix expression that is currently always true From: Colin Ian King <colin.king@...onical.com> The || condition in hdev->fd_active_type != HCLGE_FD_ARFS_ACTIVE || hdev->fd_active_type != HCLGE_FD_RULE_NONE will always be true because hdev->fd_active_type cannot be equal to two different values at the same time. The expression is always true which is not correct. Fix this by replacing || with && to correct the logic in the expression.
