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!
