The "factory" (in-kernel) driver under stress will hang and reset quite reliably on 2.5G LAN ports, particularly if you try to use two of them in a= box as a gateway/firewall. Its severe enough that I consider these ports to be unusable under FreeBSD although I have one in my Windows desktop machine and under Windows it works acceptably-well, including under fairly-extreme stre= ss (e.g. image backups, rendering video to network drives, etc.) all at 2.5G speeds. --=20 You are receiving this mail because: You are the assignee for the bug.=
