Subject: [dpdk-dev] [PATCH 1/2] net/bnxt: make offload flags mapping per-ring
Date: Fri, 18 Dec 2020 15:28:36 -0500 [thread overview]
Message-ID: <20201218202837.2074736-2-lance604@gmail.com> (raw)
In-Reply-To: <20201218202837.2074736-1-lance604@gmail.com>
From: Lance Richardson <lance.richardson@broadcom.com>
Refactor offload flags mapping table to be dynamic and
per-ring instead of static and global.
