Subject: [dpdk-dev] [PATCH 09/44] event/octeontx2: support linking queues to ports
Date: Sun, 2 Jun 2019 00:23:19 +0530
Message-ID: <20190601185355.370-10-pbhagavatula@marvell.com> (raw)
In-Reply-To: <20190601185355.370-1-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.
