I have been recently testing 3C996B-T board in an Athlon system. The system has TigerMP board and a single Athlon 2000+ and runs FreeBSD 4.7-RC. With bge driver, every thing works fine except that the NIC piles up bad checksums on TCP receive packets. For instance, netperf TCP_STREAM from another machine would pile up bad checksums. What is most amazing to me is that NIC works fine with UDP receive packets. As far as I have experienced, TCP/UDP checksumming in NIC should have little or no difference. Too bad that the firmware is under NDA. I am wondering if any one had this problem. Any help will be greatly appreciated.
