6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Carolina Jubran <cjubran@xxxxxxxxxx>
[ Upstream commit c88146abe4d0f8cf659b2b8883fdc33936d2e3b8 ]
Ensure the scheduling element type and TSAR type are explicitly
initialized in the QoS rate group creation.
This prevents potential issues due to default values.
Fixes: 1ae258f8b343 ("net/mlx5: E-switch, Introduce rate limiting groups API")
