v7:
* Refer to andrew's suggestion:
  - Add DMA_INTR_ENA_NIE_RX and DMA_INTR_ENA_NIE_TX #define's, etc.

* Others:
  - Using --subject-prefix="PATCH net-next vN" to indicate that the
    patches are for the networking tree.
  - Rebase to the latest networking tree:
    <git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git>


v6:

* Refer to Serge's suggestion:
  - Add new platform feature flag:
    include/linux/stmmac.h:
    +#define STMMAC_FLAG_HAS_LGMAC			BIT(13)

  - Add the IRQs macros specific to the Loongson Multi-channels GMAC:
     drivers/net/ethernet/stmicro/stmmac/dwmac_dma.h:
     +#define DMA_INTR_ENA_NIE_LOONGSON 0x00060000	/* Normal Loongson Tx/Rx Summary */
     #define DMA_INTR_ENA_NIE 0x00010000	/* Normal Summary */
     ...

  - Drop all of redundant changes that don't require the
    prototypes being converted to accepting the stmmac_priv
    pointer.

* Refer to andrew's suggestion:
  - Drop white space changes.
  - break patch up into lots of smaller parts.
     Some small patches have been put into another series as a preparation
     see <https://lore.kernel.org/loongarch/cover.1702289232.git.siyanteng@loongson.cn/T/#t>
     
     *note* : This series of patches relies on the three small patches above.
* others
  - Drop irq_flags changes.
  - Changed patch order.


v4 -> v5:

* Remove an ugly and useless patch (fix channel number).
* Remove the non-standard dma64 driver code, and also remove
  the HWIF entries, since the associated custom callbacks no
  longer exist.
* Refer to Serge's suggestion: Update the dwmac1000_dma.c to
  support the multi-DMA-channels controller setup.
