[安宏奎]

For the question one, maybe you can detect it before binding to igb_uio

主题: [dpdk-dev] Port-ids and NIC features

Dear all,

Two quick questions:

1) Is there a way to get the features available in the NIC? In particular, I
cannot see a way to retrieve the *maximum speed* of the card and I need to
determine whether is a FE, GE or 10GE card.

2) For a certain number of NICs installed in the system and bound to the
IGB_UIO driver, is it safe to assume that the association phyisical port <->
port_id will always be the same? Even after reboot, and regardless of the
order that are bound to the IGB_UIO driver (e.g. using pci_unbind.py)?

Best
marc
