From: Gaetan Rivet Date: Sun, 9 Jul 2017 01:44:45 +0000 (+0200) Subject: ethdev: save VLAN filter setting X-Git-Tag: spdx-start~2539 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=4188620d02f088a93867ae7d13dd8b7f13533bfc;p=dpdk.git ethdev: save VLAN filter setting In order to be able to replicate a configuration onto a second port, device configuration should be fully described and available. Other configuration items (i.e. MAC addresses) are stored within rte_eth_dev_data, but not this one.
