Subject: [dpdk-dev] [PATCH v2 4/4] cfgfile: check flags value
Date: Fri, 24 Apr 2020 10:15:36 -0700 [thread overview]
Message-ID: <20200424171536.11535-5-stephen@networkplumber.org> (raw)
In-Reply-To: <20200424171536.11535-1-stephen@networkplumber.org>
All API's should check that they support the flag values
passed. If an application passes an invalid flag it could
cause problems in later ABI.
