Hi,

struct ifnet has if_baudrate (which is actually if_data.ifi_baudrate),
member, but where is the member used?

Should it be initilized to proper values in attachments of each driver?
Or is it initialized in the MII layer later?

Currently only a few drivers have it, and if it isn't initialized
in the driver attacments, it will be set to default 10Mbps in
sys/net/if_ethersubr.c:ether_ifattach().
I wonder if we should set it to proper speed manually or not.
