Hi, laurent.hardy

  You are the author for the patch (* net/ixgbe: ensure link status is

updated), why do you implement code that way?

Is that must that  set up link with wait?



ixgbe_setup_link(hw, speed, true);



The main issue which has lead to this patch has been reported through a test

case with the autoneg enabled (which has been also reported in the pmd

test provided along with the patch:

http://patches.dpdk.org/comment/46253/).

In this context, without the flag set the patch wasn't effective.



My question is whether we can change to:



ixgbe_setup_link(hw, speed, false);



in your patch, it is " ixgbe_setup_link(hw, speed, true);"

some user may  need flexible in wait for complete.




Yes, the parameter (autoneg_wait_to_complete) could be change to false.
I redo the test following test plan provided through http://patches.dpdk.org/comment/46253/, with flag set to false
and speed defined to 1Gb on switch side.
In this case both ports goes properly up (nic used is 82599ES 10-Gigabit) with a correct link speed.

Thank you for your test and feedback!
