sys/dev/bge if_bge.c if_bgereg.h
Add bge(4) support for big-endian architectures(part 1/2).
- Give up endianess support and switch to native-endian format for
accessing hardware structures. In fact embedded processor for
BCM57xx is big-endian architure(MIPS) and it requires native-endian
format for NIC structures.The NIC performs necessary byte/word
swapping depending on programmed endian type.
- With above changes all htole16/htole32 calls were gone.
- Remove bge_vhandle member in softc and changed to use explicit
register access. This may add additional performance penalty
that than that of previous memory access. But most of the access
is performed on initialization phase(e.g. RCB setup), it would be
Due to incorrect use of bus_dma(9) in bge(4) it still panics sparc64
system in device detach path. The issue would be fixed in next patch.
