Subject: [dpdk-dev] [PATCH 6/9] common/cnxk: support changing drop re flag after lf alloc
Date: Tue, 2 Nov 2021 21:24:17 +0530 [thread overview]
Message-ID: <20211102155421.486-6-ndabilpuram@marvell.com> (raw)
In-Reply-To: <20211102155421.486-1-ndabilpuram@marvell.com>
Add API to toggle drop_re flag after nix_lf_alloc() so that it
can be used to toggle it runtime.
