Subject: [dpdk-stable] [PATCH v2] net/ixgbe: fix macsec setting
Date: Tue, 29 Oct 2019 16:32:11 +0000
Message-ID: <20191029163211.3254-1-guinanx.sun@intel.com> (raw)
In-Reply-To: <20191025092140.37288-1-guinanx.sun@intel.com>

macsec setting is not valid when port is stopped.
In order to make it valid, the patch changes the setting
to where port is started.

Fixes: 597f9fafe13b ("app/testpmd: convert to new Tx offloads API")
Cc: stable@dpdk.org

Signed-off-by: Sun GuinanX <guinanx.sun@intel.com>

v2:
* Modified function name
* Refactored the rte_pmd_ixgbe_macsec_enable/disable function
* Modified structure name
* Modified the data type of a structure variable
