--- Comment #2 from Sean Bruno <sbruno at FreeBSD.org> ---
Current code now reflects the request in this ticket:

if_ix.c:

        /*
         * Workaround: mprc hardware is incorrectly counting
         * broadcasts, so for now we subtract those.
         */
        bprc = IXGBE_READ_REG(hw, IXGBE_BPRC);
        adapter->stats.pf.bprc += bprc;
        adapter->stats.pf.mprc += IXGBE_READ_REG(hw, IXGBE_MPRC);
        if (hw->mac.type == ixgbe_mac_82598EB)
                adapter->stats.pf.mprc -= bprc;
