Subject: [PATCH V2 net 3/4] net: hns3: fixed vf get max channels bug
From: Jian Shen <shenjian15@...wei.com>
Currently, the queried maximum of vf channels is the maximum of channels
supported by each TC. However, the actual maximum of channels is
the maximum of channels supported by the device.
Fixes: 849e46077689 ("net: hns3: add ethtool_ops.get_channels support for VF")
