[dpdk-dev] [PATCH v4 1/2] app/testpmd: fix Tx VLAN and QinQ dependency

[Nithin Dabilpuram <nithind1988@gmail.com>]

From: Nithin Dabilpuram <ndabilpuram@marvell.com>

Tx VLAN & QinQ insert enable need not depend on
Rx VLAN offload ETH_VLAN_EXTEND_OFFLOAD. For Tx VLAN
insert enable, error check is now to see if QinQ was enabled
but only single VLAN id is set.

Fixes: 6a34f91690d0 ("app/testpmd: fix error message when setting Tx VLAN")

v4:
* Resend v3 from different mailserver to avoid 
  CRLF
v3:
* Add back error check in tx_vlan_set() to check if QinQ is
already enabled. Also fix headline.
v2:
* Split change into two seperate patches as suggested.
