Subject: net/mlx5: Clear bw_share upon VF disable
From: Vladyslav Tarasiuk <vladyslavt@xxxxxxxxxx>
[ Upstream commit 1ce5fc724a26e0b476e42c5d588bdb80caea003b ]
Currently, if user disables VFs with some min and max rates configured,
they are cleared. But QoS data is not cleared and restored upon next VF
enable placing limits on minimal rate for given VF, when user expects
none.
To match cleared vport->info struct with QoS-related min and max rates
upon VF disable, clear vport->qos struct too.
Fixes: 556b9d16d3f5 ("net/mlx5: Clear VF's configuration on disabling SRIOV")
