Subject: [dpdk-dev] [PATCH v4 8/8] net/tap: add flow control management
Date: Tue, 14 Mar 2017 09:22:52 +0100 [thread overview]
Message-ID: <8de3e22a7f1d288c0ffe72f453b08a8cdb875f3a.1489479553.git.pascal.mazon@6wind.com> (raw)
In-Reply-To: <cover.1489479553.git.pascal.mazon@6wind.com>
A tap netdevice does not support flow control; ensure nothing but
RTE_FC_NONE mode can be set.
Signed-off-by: Pascal Mazon <pascal.mazon@6wind.com>
