From: Guangbin Huang <huangguangbin2@huawei.com> mainline inclusion from mainline-v5.13-rc1 commit 57a8f46b1bd3f5f43b06f48aab7c1f7ca0936be3 category: feature bugzilla: 173966 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... ---------------------------------------------------------------------- When the imp-controlled PHYs feature is enabled, phydev is NULL. In this case, the autoneg is always off when user uses ethtool -a command to get pause parameters because hclge_get_pauseparam() uses phydev to check whether device is TP port. To fit this new feature, use media type to check whether device is TP port. And when user set pause parameters, these parameters need to always set to mac, no matter whether autoneg is off.
