Hi! Patch fixes several bugs in bge(4) and makes it work on any platforms. Patch changes . Give up endianness access and switch to native endian format while accessing hardware. Since I don't have data sheet of Tigon3 I can't sure it's possible to use endianness access but NetBSD/OpenBSD also uses native endian format and data sheet for Tigon1/Tigon2 explicitly says that it requires native endian access. [1] . Remove rman_get_virtual(9) and use bus_space_write_4(9). [1] . Change return code of bge_eeprom_getbyte() when timeout error occurrs. [2] . Add a mutex to protect jumbo frame list handling such that jumbo frame now works on SMP. . ifdef out "no free jumbo buffers" printf calls as numerous printf messages make system unusable under jumbo buffer shortage. It's well demonstrated with netperf UDP tests. . Don't invoke bus_dmamap_destroy(9) for DMA maps which were created with bus_dmamem_alloc(9). . Add missing bus_dmamap_sync(9) in bge_txeof(). . Add missing bus_dmamap_sync(9) in bge_encap(). . Use #ifndef __NO_STRICT_ALIGNMENT instead of #ifndef __i386__ to check whether target system is strict alignment architecture. . Use callout_init_mtx(9) and add callout_drain(9) to bge_detach(). . Reorder detach path so have detach work. . Reject driver detach when there are any references to jumbo buffers. Previously it was lead to reference to freed memory. [1] : Obtained from OpenBSD via NetBSD. [2] : Submitted by jkim. The patch can be obtained from: http://people.freebsd.org/~yongari/bge.patch.0908 The patch was reviewed by marius and jkim and tested on i386(SMP), sparc64(SMP), amd64. Thanks. -- Regards, Pyun YongHyeon
