    msk(4): Align TX buffer to 64bytes boundary instead of 8bytes boundary
    The correct alignment boundary is found out by using busdma(9)'s
    alignment constraint.  However, it seems that using in-place copy
    results in better performance than let busdma(9) to bounce misaligned
    TX buffer, especially with tiny packets; probably due to the "in-place"
