Hi Greg, the 2.5 Gbit/s NIC is downwards compatible with 1 Gbit/s Ethernet and while there is not much supporting equipment, it is no worse than a 1 Gbit/s NIC in practice. 10 Gbit/s is too expensive (due to chip and board complexities) and to power-hungry for integration on typical PC mainboards (given the high cost of 10 Gbit/s switches, hardly anybody could make good use of them outside a datacenter environment, anyway). You do probably know that the Realtek RTL8125 chip is supported by the official Realtek driver in ports (realtek-re-kmod package). Too bad that Realtek does not publish programming information for this chip. There are open source drivers that support it, but they do not fit well into FreeBSD and they do not provide sufficient information to make the FreeBSD Realtek 1 Gbit/s NIT driver support the 2.5 Gbit/s chip ... (I had started a merge of the code for the new chip into our kernel driver, but there was not enough information about the PHY and other details and I gave up.) Every few month I look for a publicly available databook with the necessary details (full register description, reset sequence etc.) for the RTL8125 chips on the sites that tend to provide such information, but nothing has appeared there, yet. Best regards, STefan
