Subject: [PATCH net-next 07/14] mlxsw: reg: Increase MLXSW_REG_QEEC_MAS_DIS

From: Petr Machata <petrm@...lanox.com>

As the port speeds grow, the current value of "unlimited shaper",
200000000Kbps, might become lower than the actually supported speeds. Bump
it to the maximum value that fits in the corresponding QEEC field, which is
about 2.1Tbps.
