The offload flags variable (ol_flags) in rte_mbuf structure is 64-bits,
so local copy of it must be 64-bits too. Moreover bit comparison between
16-bits variable and 64-bits value make no sense. This breaks Tx vlan
IP and L4 offloads.
CID 13218 : Operands don't affect result (CONSTANT_EXPRESSION_RESULT)
result_independent_of_operands: ol_flags & (18014398509481984ULL /* 1ULL
<< 54 */) is always 0 regardless of the values of its operands. This
occurs as the logical operand of if.

This is essentially patch http://www.dpdk.org/dev/patchwork/patch/12642
applied after the enic_send_packet function was melded into the main
transmit funciton.
