stmmac_tso_xmit() fills the MSS context descriptor and stores the new MSS
in tx_q->mss right away, but the descriptor only gets its OWN bit much
later, right before the frame is handed to the DMA. Every error path in
between - the dma_map_single() of the linear part and the
skb_frag_dma_map() of each fragment - returns with tx_q->mss already
updated while the MAC is still programmed with the previous MSS.
