| Subject: mlxsw: spectrum: Init shaper for TCs 8..15 |
| |
| From: Petr Machata <petrm@mellanox.com> |
| |
| [ Upstream commit a9f36656b519a9a21309793c306941a3cd0eeb8f ] |
| |
| With introduction of MC-aware mode to mlxsw, it became necessary to |
| configure TCs above 7 as well. There is now code in mlxsw to disable ETS |
| for these higher classes, but disablement of max shaper was neglected. |
| |
| By default, max shaper is currently disabled to begin with, so the |
| problem is just cosmetic. However, for symmetry, do like we do for ETS |
| configuration, and call mlxsw_sp_port_ets_maxrate_set() for both TC i |
| and i + 8. |
