Subject: [PATCH net-next v2 4/7] testing: selftests: drivers: net: netdevsim: devlink: add test case for hard drop statistics
Date: Mon, 14 Jun 2021 16:01:15 +0300	[thread overview]
Message-ID: <20210614130118.20395-5-oleksandr.mazur@plvision.eu> (raw)
In-Reply-To: <20210614130118.20395-1-oleksandr.mazur@plvision.eu>

Add hard drop counter check testcase, to make sure netdevsim driver
properly handles the devlink hard drop counters get/set callbacks.
