Subject: [dpdk-dev] [PATCH 2/2] net/tap: replace offload_capa function with define
Date: Tue, 15 Jun 2021 21:15:28 -0700	[thread overview]
Message-ID: <20210616041528.4229-3-stephen@networkplumber.org> (raw)
In-Reply-To: <20210616041528.4229-1-stephen@networkplumber.org>

Since the offload values are always the same, these can
just be data instead of code.
