A driver must not access the two fields directly but should instead use
the helper functions to set the values and keep a consistent internal
state:

ethernet/stmicro/stmmac/stmmac_main.c: In function 'stmmac_dvr_probe':
ethernet/stmicro/stmmac/stmmac_main.c:4083:8: error: 'struct net_device' has no member named 'real_num_rx_queues'; did you mean 'real_num_tx_queues'?

Fixes: a8f5102af2a7 ("net: stmmac: TX and RX queue priority configuration")

Applied.

This break my revert patch. (since it patch ("net: stmmac: enable multiple buffers").
Since dwmac-sunxi is still broken, what can I do ? send two revert patch ? or adapt the reverting patch.

Have you tried if the kcalloc() patch I sent on Tuesday fixes things the
issues introduced by the multiple buffers patch? Niklas reported that it
restores functionality on his setup.

I think he said yesterday that he did indeed test all of your patches and it
did not fix things for him.

I am going to revert the enable multiple buffers commit, and I would ask that
all involved parties work together in the background to resolve all of this.

@David: Could you please create a branch in your git tree for us to work on it
until the multiple buffers get stable for everyone? This way the patches could
circulate in the mailing-list with a different target, like stmmac-next or similar.

What do you think?

Thank you.

@David: Agreed.

@Corentin: Please check if the DMA Engine is well configured and if the dma
rx/tx has started. This is done by dumping the DMA Registers.
Please also check the MAC related registers and dump them in order to have a
clear picture if the IP is being well configured.
This is critial to analise what's hapenning in your setup.
