Subject: [dpdk-dev] DPDK 2.0.0 above detecting VFs of 10 NIC as 1G ports
Date: Thu, 3 Sep 2015 17:49:20 +0500	[thread overview]
Message-ID: <CALOK9fLwEP72xODw2c3uNDsVyVP_MZxo7zBxCpvjdVdANf9dbw@mail.gmail.com> (raw)

Hi

I am using VFs of Intel Dual port Ethernet Adapter x540 with DPDK 2.0.0.

While using DPDK, the x540 VFs are detected as 1G devices.
The information of port 0 by PMD driver is this:
PMD: eth_ixgbevf_dev_init(): port 0 vendorID=0x8086 deviceID=0x1515
mac.type=ixgbe_mac_82599_vf

To check the link speed, I used this simple code:
struct rte_eth_link rte_eth_link;
rte_eth_link_get(0, &rte_eth_link);
and the value of "rte_eth_link.link_speed" is ETH_LINK_SPEED_1000.

Why is DPDK detecting the VF as 1G device and not 10G? Can I change this
behavior?

Thanks for your time.

Regards
Umar
