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.

If it makes things work for you as well, we could maybe avoid the revert
altogether.

Thierry, I know that you are using DWMAC CORE 4.XX
How many RX queues and how many TX queues have you got?

I'm also using DWMAC CORE 4.XX
We have 2 TX queues and 1 RX queue.

I think that Corentin is using DWMAC CORE 3.XX

I know that Joao is using an IP Prototyping Kit that uses
DWMAC CORE 4.XX (connected via PCIe).
It would be nice if Joao could get an IP Prototyping Kit
based on DWMAC CORE 3.XX.

Doesn't Synopsys have an IP Prototyping Kit based on
DWMAC CORE 3.XX laying around somewhere? :)

I requested a prototyping platform with MAC 100 or a MAC 1000 in order to make
more tests, but I don't have an ETA for it yet.

The implication of the multiple buffers patch in 3.xx is some flow change in the
configuration of dma op mode or similar. I would recomend Corentin to dump the
dma & mac registers in the end of the _open function in order to see if the DMA
is really being well configured and is really started.

Thanks.

Joao
