    net: fix signed shift overflow in IPv6 checksum
    
    In rte_ipv6_phdr_cksum() the next header field, a uint8_t, is promoted to
    a signed int before the left shift by 24. For protocol values >= 128
    (for example IPPROTO_SCTP), proto << 24 does not fit in int, which is
    undefined behaviour (signed left shift overflow) reported by UBSan:
    
      rte_ip6.h: runtime error: left shift of 132 by 24 places cannot be
      represented in type 'int'
    
    Cast the operand to uint32_t before the shift so it is performed in
    unsigned arithmetic. The resulting value is unchanged on two's
    complement platforms. The same idiom is already used in RTE_IPV4().
    
    Fixes: 6006818cfb26 ("net: new checksum functions")
