Hi All, There is a bug in the DP8393X emulation that can stop packet reception.
Whilst debugging that issue I found that the receiver algorithm differs from the one described in the National Semiconductor datasheet. These issues and others are addressed by this patch series. This series has only been tested with Linux/m68k guests. It needs further testing with MIPS Jazz guests such as NetBSD or Windows NT. Thanks.
