[PATCH][next] net: hns3: fix expression that is currently always true

From: Colin King
Date: Mon Dec 14 2020 - 19:01:52 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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.

Addresses-Coverity: ("Constant expression result")
Fixes: 0205ec041ec6 ("net: hns3: add support for hw tc offload of tc flower")
