The mvneta BM can't work on 64bit platform, as the BM hardware expects buf virtual address to be placed in the first four bytes of mapped buffer, but obviously the virtual address on 64bit platform can't be stored in 4 bytes. So we have to explicitly disable BM on 64bit platform. Signed-off-by: Jisheng Zhang <redacted> --- drivers/net/ethernet/marvell/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
