Subject: [dpdk-dev] [PATCH v3 09/42] event/octeontx2: support linking queues to ports
Date: Fri, 28 Jun 2019 23:53:20 +0530 [thread overview]
Message-ID: <20190628182354.228-10-pbhagavatula@marvell.com> (raw)
In-Reply-To: <20190628182354.228-1-pbhagavatula@marvell.com>
From: Pavan Nikhilesh <pbhagavatula@marvell.com>
Links between queues and ports are controlled by setting/clearing GGRP
membership in SSOW_LF_GWS_GRPMSK_CHG.
