In commit 9ffcc3725f09 ("mlxsw: spectrum: Allow packets to be trapped
from any PG") I fixed a problem where packets could not be trapped to
the CPU due to exceeded shared buffer quotas. The mentioned commit
explains the problem in detail.
The problem was fixed by assigning a minimum quota for the CPU port and
the traffic class used for scheduling traffic to the CPU.
However, commit 117b0dad2d54 ("mlxsw: Create a different trap group list
for each device") assigned different traffic classes to different
packet types and rendered the fix useless.
Fix the problem by assigning a minimum quota for the CPU port and all
the traffic classes that are currently in use.
Fixes: 117b0dad2d54 ("mlxsw: Create a different trap group list for each device")
