    net: fix packet type for stacked VLAN
    
    The rte_net_get_ptype() supported only 2 types of VLAN headers frames
    that are defined in the IEEE standards 802.1Q and 802.1ad:
    
    frames with a single 0x8100 VLAN header:
      eth type VLAN / vlan / [IPv4 | IPv6 ]
    
    frames with 0x88A8 QinQ header followed by 0x8100 VLAN:
     eth type QinQ / vlan type VLAN / vlan / [IPv4 | IPv6 ]
    
    The function did not parse frames where VLAN headers were stacked in
    different configurations.
    Such frames should also be allowed to provide HW vendor flexibility.
    As a result, ptype bitmask and header length returned from
    rte_net_get_ptype() for a custom VLAN frame were wrong.
    
    For example, the parser result for the frame
      eth type QinQ / vlan type QinQ / vlan type VLAN / vlan / ipv4
    was:
    pkt_type:=0x120007
       RTE_PTYPE_L2_ETHER_QINQ         0x00000007 OK
       RTE_PTYPE_INNER_L2_ETHER_VLAN   0x00020000 wrong
       RTE_PTYPE_INNER_L3_IPV4         0x00100000 wrong
    
    hdr_lens:={
      l2_len       = 22 wrong
      inner_l2_len =  4 wrong
      l3_len       =  0 wrong
      inner_l3_len = 20 wrong
    }
    
    The patch changes:
    1. Allow frames with up to RTE_NET_VLAN_MAX_DEPTH:=8
       number of VLAN headers.
    
    2. Set each parsed VLAN type in the returned ptype bitmask.
       Multiple VLAN headers are referenced by a single
       RTE_PTYPE_L2_ETHER_VLAN bit.
       Multiple QinQ headers are references by a single
       RTE_PTYPE_L2_ETHER_QINQ bit.
    
    3. Preserve RTE_PTYPE_L2_ETHER bit if VLAN or QinQ type was detected.

    Fixes: 218a163efd67 ("net: support QinQ in software packet type parser")
