#Test1 is just a simple test. Just launch testpmd with these nic port.
./testpmd –c 0x3 –n 4 -- -i

I didn’t quite get your points, I observed that after applying this patchset, all intel nic can’t be started, maybe something wrong happened when you check the duplex/autoneg value for different NICs. If we want to merge the patchset in RC2, we need fix them. Maybe not an easy job in several days.

Is this test#1 one of the tests contained in the DPDK repository or is it an internal test?

2016-03-17 19:08, Thomas Monjalon:

There are still too few tests and reviews, especially for
autonegotiation with Intel devices (patch #6).
I would not be surprised to see some bugs in this rework.

Any feedback about autoneg in e1000/ixgbe/i40e?
Has it been tested before its integration in RC2?

The capabilities must be adapted per device. It can be improved in a
separate patch.

It will be integrated in 16.04-rc2.
Please test and review shortly, thanks!

Subject: RE: DPDK link speed with Intel devices
Hi, all
We have worked out the basic test cases for the patchset.
1. Test the link speed on major Intel NICs to see if the speed is right.
2. Test the auto-negoation on major Intel NICs to ensure it's working.
Nic covered: ixgbe, igb, i40e, fm10k, bonding(SW), virtio(SW)

When we run the Test#1 for all major NICs. We found that all these NIC port(igb, ixgbe, i40e, fm10k) can't be started. Pls check, if the patch is applied, all INTEL port can't be start, terrible things!

Interactive-mode selected
Configuring Port 0 (socket 0)
PMD: ixgbe_dev_tx_queue_setup(): sw_ring=0x7f13e99e3440 hw_ring=0x7f13e99e5480 dma_addr=0x8299e5480
PMD: ixgbe_set_tx_function(): Using simple tx code path

PMD: ixgbe_dev_start(): Invalid link_speeds for port 0; autonegotiation disabled
Fail to start port 0
Configuring Port 1 (socket 0)
PMD: i40e_set_tx_function_flag(): Vector tx can be enabled on this txq.
PMD: i40e_dev_rx_queue_setup(): Rx Burst Bulk Alloc Preconditions are satisfied. Rx Burst Bulk Alloc function will be used on port=1, queue=0.
PMD: i40e_dev_start(): Invalid link_speeds for port 1; autonegotiation disabled


Just to double-check; is the test#1 adapted to the _new_ API that ethdev has to set link speeds? For the output it seems autoneg is disabled => fixed speed, hence the new bitmaps have to be used.

(I am not claiming patchset is bug free; there might be issues still)

marc

Fail to start port 1
Please stop the ports first
Done

Thanks

Hi Mike,

        We just knew this patch set last week.
        Since this patch set is required to test with a lot of NIC,  we need more document from Dev about this patch.
        Currently, Qian is working on with Wenzhuo on it now.

Waterman

Hi,

We are still waiting for test feedbacks for this important patchset:
        ethdev: 100G and link speed API refactoring It is possible that it breaks the autonegotiation in e1000/ixgbe/i40e.

Thanks for taking care.
