Subject: [dpdk-dev] [PATCH 34/44] event/octeontx2: allow adapters to resize inflight buffers
Date: Sun, 2 Jun 2019 00:23:44 +0530
Message-ID: <20190601185355.370-35-pbhagavatula@marvell.com> (raw)
In-Reply-To: <20190601185355.370-1-pbhagavatula@marvell.com>

From: Pavan Nikhilesh <pbhagavatula@marvell.com>

Add internal SSO functions to allow event adapters to resize SSO buffers
that are used to hold in-flight events in DRAM.
