The private structure contain a pointer to phydev, but the structure net_device already contain such pointer. So we can remove the pointer phydev in the private structure, and update the driver to use the one contained in struct net_device. Signed-off-by:

Broadcom buses may have more than 1 Ethernet device. This is used e.g. to have few interfaces connected to different switch ports. So far we saw chipsets with only 2 devices (e.g. BCM4706) but recent ones have up to 3 (e.g. Netgear R8000 uses 3rd interface for most of switch traffic, lower interfaces are for some kind of offloading).

The ring size is always known at compile time, so make the code a bit more efficient Signed-off-by:
-
Felix Fietkau authored
The driver needs to inform the hardware about the first invalid (not yet filled) rx slot, by writing its DMA descriptor pointer offset to the BGMAC_DMA_RX_INDEX register. This register was set to a value exceeding the rx ring size, effectively allowing the hardware constant access to the full ring, regardless of which slots are initialized. To fix this issue, always mark the last filled rx slot as invalid. Signed-off-by:

Always poll rx and tx during NAPI poll instead of relying on the status of the first interrupt. This prevents bgmac_poll from leaving unfinished work around until the next IRQ. In my tests this makes bridging/routing throughput under heavy load more stable and ensures that no new IRQs arrive as long as bgmac_poll uses up the entire budget. Signed-off-by:

There are two reasons for having this header in the common place: 1) Simplifying drivers that read NVRAM entries. We will be able to safely call bcm47xx_nvram_* functions without #ifdef-s. 2) Getting NVRAM driver out of MIPS arch code. This is needed to support BCM5301X arch which also requires this NVRAM driver. Patch for that will follow once we get is reviewed. Signed-off-by:
