[P4-dev] Questions for 'egress port TX Link utilization' (INT metadata) in BMv2

Hello everyone,

I'm trying to write an INT application that monitors 'egress port tx
utilization' (defined as baseline metadata in INT spec) based on switch.p4
+ bmv2 (simple_switch.cpp).

However, I found that bmv2 does not support 'egress port tx utilization' as

Is there any way to obtain this information from the bmv2 without modifying
If it is required to modify 'simple_siwtch.cpp', any advises to do this
would be very helpful.

Thanks in advance.
Dongeun Suh.
