Hi
Have you people experienced a situation where in Debian Ethernet link speed
settles for 100 Mb/s even when it is connected to a gigabit port on a
switch. I have checked the switch configuration and found that to be on
auto status for link speed. I used the ethtool on debian and it says that
I am connected to 100 Mb/s link.

At this point I am very much confused. The closest I came to was this
