Andrew, please apply/forward upstream. The following set of 21 patches (!) are all aimed at the the spidernet ethernet device driver. The spidernet is an etherenet controller built into the Toshiba southbridge for the PowerPC Cell processor. (This is the only device in existance that with this ethernet hardware in it). These patches re-package/re-order/re-cleanup a previous set of patches I've previously mailed. Thus, some have been previously Acked-by lines, most do not. Most of these patches are tiny, and handle problems that cropped up during testing. Sorry about there being so many of them. The first set of 12 patches fix a large variety of mostly minor bugs. The important patches are 13 through 17: these overcome a debilitating performance problem on transmit (6 megabits per second !!) on transmit of patches 500 bytes or larger. After applying these, I am able to get the following: pkt sz speed (100K buffs) speed (4M buffs) ------ ----------------- ---------------- 1500 700 Mbits/sec 951 Mbits/sec 1000 658 Mbits/sec 770 800 600 648 500 500 500 300 372 372 60 70 70 Above buf size refers to /proc/sys/net/core/wmem_default ---- I'm not planning on any further patches for a long while. I tried to do som RX work, but gave up. RX performance could be improved. FYI, Christoph Hellwig's node-aware patches seem to make no difference at all any more. I tried to base these on linux-2.6.19-rc1-mm1 but hit a kernel BUG in copy_fdtable at fs/file.c:138!
