From: Helin Zhang Date: Thu, 11 Jun 2015 07:03:58 +0000 (+0800) Subject: app/testpmd: add qinq stripping and insertion X-Git-Tag: spdx-start~8863 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=92ebda07ee58cf6966305ba03b50b81debfb2d98;p=dpdk.git app/testpmd: add qinq stripping and insertion If double vlan is detected, its stripped flag and vlan tags can be printed on rxonly mode. Test command of 'tx_vlan set' is expanded to set both single and double vlan tags on TX side for each packets to be sent out.
