Description Wojciech Puchar 2017-08-12 11:51:26 UTC 
Intel 10Gbe interface (ix driver)  cannot link at 1Gb/s to a switch IF any vlan on that interface is enabled. With no vlan enabled it connects fine.

Temporary workaround is to delay creating vlans until link is up.

as for switch type i wait for response - not my switch, i'm not physically close to the machine.

switch is Extreme x450a-48T, latest firmware. port is set up to force gigabit.
