mlxsw: spectrum_buffers: Forbid changing threshold type of first egress pool (51e15a49) · Commits · 戴 / test

Multicast packets have three egress quotas: * Per egress port * Per egress port and traffic class * Per switch priority The limits on the switch priority are not exposed to the user and specified as dynamic threshold on the first egress pool. Forbid changing the threshold type of the first egress pool so that these limits are always valid. Signed-off-by:
