Jose Abreu 0431100b3d net: stmmac: Fixup the tail addr setting in xmit path ... Currently we are always setting the tail address of descriptor list to the end of the pre-allocated list. According to databook this is not correct. Tail address should point to the last available descriptor + 1, which means we have to update the tail address everytime we call the xmit function. This should make no impact in older versions of MAC but in newer versions there are some DMA features which allows the IP to fetch descriptors in advance and in a non sequential order so its critical that we set the tail address correctly.
