[PATCH (net-next.git) 07/18] stmmac: add is_jumbo field to dma data

Optimize tx_clean by avoiding a des3 read in stmmac_clean_desc3(). In ring mode, TX, des3 seems only used when xmit a jumbo frame. In case of normal descriptors, it may also be used for time stamping. Clean it in the above two case, without reading it. Signed-off-by: Fabrice Gasnier Signed-off-b
