[dpdk-dev] [PATCH] bonding: add QinQ packet xmit hash support

[Chas Williams]

I think this change already went in dpdk-next-net:

    net/bonding: add support to match on 0x88A8 ethertype

    We assume VLAN ethtertype is 0x8100 in get_vlan_offset() function,
    but it could be 0x88A8 if QinQ is supported.

    Fixes: 06fe78b98ccd ("bond: add mode 6")
