Subject: Re: [PATCH v2 5/5] dts: add `show port stats` command to TestPmdShell
Date: Mon, 20 May 2024 10:26:13 -0400	[thread overview]
Message-ID: <CAKXZ7eirx1irXMDC5iP=xO1Vo_R7pt=zrMuL1qfX89x1EMqegA@mail.gmail.com> (raw)
In-Reply-To: <20240509112635.1170557-6-luca.vizzarro@arm.com>

I've been running some local tests using a mock test suite. Each
method you created generates output as expected, but
show_port_stats_all() is printing out an empty list; I'm not sure this
is intentional or not. I don't have much experience with regular
expressions to be able to discern what is going on in the code within
a reasonable amount of time, so I wanted to bring this to your
attention.
