Message 'receive fifo overflow' appeared in the log. Root cause was an invalid physical address being programmed into the DMA engine. This was caused by an invalid pointer cast in the dma code. Issue was observed on a Sparc (Sun Fire V120) machine but could theoretically also pop up on other architectures. Driver was tested to scan and ping on aforementioned machine. Reviewed-by:

Problem would pop up during driver load on a Sun Fire V120 and manifested itself as an exception. This was caused by int* pointers provided to memcpy() that were not aligned on an int boundary. The pointer type provided to memcpy() is used by the compiler for optimization purposes. Fix was to cast the int* pointers to void* pointers. Bernhard R. Link and David S. Miller provided valuable feedback, thanks gents. Reviewed-by:

When bringing down the netdevice interface a deadlock occurred sporadically due to the rtnl_lock being held by a task that was waiting for another task trying to get the lock. This patch fixes that issue. Reviewed-by:

brcmsmac doesn't yet use bcma, but both drivers attempt to claim the same device. For now, turn of brcmsmac if bcma is enabled. Signed-off-by:

Certain Mips based, big endian Broadcom products contain a memory window for endianness swap purposes. However, this is too system specific for this driver as there are more big endian platforms to support. Thus, this 'window' functionality is not to be used and can be removed. The swap window would be a performance improvement and could be provided with a dedicated mapping function in the platform specific code. Tested on BCM63281. Reviewed-by:

The inline function dma_spin_for_len() was defined for MIPS platforms but the problem only occurs with dma of the PCI core in bcm47xx chips. This patch restricts the function further to BCM47XX platforms only. Tested on BCM63281. Reviewed-by:

The driver contained conditional code for resolving issue with dma transaction reordering. This code was conditionalized using __mips__ macro, but it actually is specific to bcm47xx chips. This patch replaces it for the more speficic CONFIG_BCM47XX macro. Tested on BCM63281. Reviewed-by:

Swapping the addresses is unnecessary, since the swaps are handled by the underlying platform code (i.e. readb() etc. handle any necessary swapping). Tested on Mac G5 PPC and BCM63281. Signed-off-by:

The macro BUS_SWAP32(a) expanded to (a) which was fine for a little endian system. For big endian platform this should do as the name implies. As the driver is intended for PCI which is little-endian the macro cpu_to_le32() can be used instead. Reviewed-by:

Four macros with PHYSADDR name prefix are not doing a lot and complicate code readability. These have been expanded in the source code and consequently removed the definitions. Reviewed-by:

The macros W_SM and R_SM are not doing much conversion of the macro parameters and complicate code readability without good cause. It is more clear to remove usage of the macros expanding it in the source code. Reviewed-by:
