I've got some DEC Miatas with DECchip 21142/43 ethernet cards, and I don't get the same link speeds when using the de4x5 and tulip drivers, as of 2.4.0-test10. The machines are connected to a Netgear 16-port 10/100 hub. With the tulip driver the hub shows a 10 Mb/s connection; with the de4x5 driver the hub shows a 100 Mb/s connection. In both cases the drivers are configured into the kernel, not as modules, if it matters.
Am I doing something wrong, or is this a known issue?
FWIW, these machines are diskless, and according to the hub they download the kernel at 100 Mb/s. When the tulip-based kernel initializes the card, the hub shows the link speed switching to 10 Mb/s.
