When the mlx5en(4) driver was converted to using BUSDMA(9) the call to m_defrag() was moved after the part of the TX routine that strips the header from the mbuf chain. Before it called m_defrag it first trimmed off the now-empty mbufs from the start of the chain. This has the side effect of also removing the head of the chain that has M_PKTHDR set. m_defrag() will not defrag a chain that does not have M_PKTHDR set, thus it was effectively never defragging the mbuf chains. As it turns out, trimming the mbufs in this fashion is unnecessary since the call to bus_dmamap_load_mbuf_sg doesn't map empty mbufs anyway, so remove it.
