    Subject[PATCH 8/9] staging: fsl-dpaa2/eth: Fix SGT allocation
    Date
    We mistakenly allocate space for too many entries in the
    scatter-gather table of multi buffer egress frames.

    While it doesn't have a negative impact from a functional
    point of view, it wastes resources so fix it.
