How intel 82599 using link flow control?Is it Auto-Negotiation？ But I seems that will not Auto-Negotiation in the intel drive.
How can I using it ?
If speed of the link 10G,it will not auto-negtiation.Driver code:
if (speed == IXGBE_LINK_SPEED_1GB_FULL) //only 1Gb will negtiation.
ret_val = ixgbe_fc_autoneg_fiber(hw);
