Hi, I have been using the following patched bfe(4) and it seems it works as expected. I've fixed long standing bus_dma(9) bugs in it and it should work on systems with > 1GB memory. In theory bfe(4) should also work on big-endian architectures. However the 1GB DMA address space of the hardware is much lower than that of DVMA base address of sparc64 so the possibility of using bfe(4) on sparc64 is zero. :-( As added bonus of patched driver, bfe(4) now supports hardware statistics counter. You can use sysctl(8) to see what counters are maintained in the hardware. For example, the following command will show detailed statistics for Tx/Rx frames. #sysctl dev.bfe.0.stats=1 If you have one of bfe(4) hardwares please give it try and let me know how it goes. The latest bfe(4) can be found at the following URL. http://people.freebsd.org/~yongari/bfe/if_bfe.c http://people.freebsd.org/~yongari/bfe/if_bfereg.h -- Regards, Pyun YongHyeon
