Hi,

The IEEE 802.1Qaz standard restricts bandwidth allocation percentages
to Enhanced Transmission Selection (ETS) traffic classes; STRICT,
VENDOR, and CB Shaper TSA types carry no bandwidth semantics.  Two
problems exist in the mlx5e DCBNL ETS implementation: the get path
reports 100% bandwidth for all TCs regardless of TSA type due to a
hardware limitation, introduced by commit 820c2c5e773d ("net/mlx5e:
Read ETS settings directly from firmware"), and the set path does
not reject the unsupported CB Shaper TSA, introduced by commit
08fb1dacdd76 ("net/mlx5e: Support DCBNL IEEE ETS").

[...]
Here is the summary with links:

You are awesome, thank you!
