Can't you read from the h/w if the link is trained?
Yes.
There are customers who use this driver with PCI Link setup done in the
boot loader. This property tells the driver to bypass Link setup
procedure in that case. Is this undesirable and if so. how other
platforms handle it? Check first if link is trained or start the link
setup procedure? Let me know. If this is fine, please provide your Ack.
Thanks.
