My thinking was that I was trying to add only what was absolutely necessary to the flow by inferring the inner tag value by slavishly following 802.1ad that specifies 0x88a8 for the outer and 0x8100 for the inner TPID.

However, your point is well taken. Also, adding the inner tpid does simplify the code so I will change it in V7.

Thanks,
