Looking at the database definitions for the NICs in both pc3001 and pcr200, I see no reason for the 100Mbs limitation. Both have max speed set to 1000. These are the first testbed machines we're used with the bge driver. I allocated an r200 with default settings and got FC8 with a 100/full experimental link. I forced the switchport to 1000, bounced the interface, and ifconfig in FC8 showed that I was now at 1000/full.
Just curious, but what is in the current_speed slot of the interfaces table for those experimental interfaces? Want to first confirm that the DB says the right thing ... Lbs
