Subject: rtk8168 driver help needed
Hi,
I am trying to integrate the rtl8168 PCIe card to have Ethernet functional on my
Keystone EVM. I purchased the rtl8111c Gib card from Amazon. The Card is detected
by the RC and I can see it is enumerated and show up when doing lspci command.
However I can't get the Ethernet port functional. Does this need MSI interrupt?
I can't see it has requested any.
