This patch-set was built in order to be easy for a developer to have a clear view of what was done to add multiple queues/channels to stmmac. It shows a progressive work starting in an initial mac functions upgrade, followed by dma related functions upgrade and finally introcuding the multiple buffers.
Some of the functions had to be broken in RX and TX related, in order to enable separated treatment, since the number of RX queues can be different from the number of TX queues for example. Each patch and the final patch-set were tested using a 4.21 EQOS IP Core.
