If you were to enter ixgbe_watchdog_link_is_up() with unknown speed, then I
would
assume that you also have a dmesg that shows:
"NIC Link is Up unknown speed"
by the interface you use in the bond?
It seems odd to be checking the MAC type for this. Is this behavior perhaps
more related to the copper phy? If so, then the check should be changed. Or
would the check for unknown link speed be sufficient? It seems like an
interface as a slave would not work with an unknown link speed, so it may as
well wait in all cases, not just for X540.

Hi, Mark
Thanks for your suggestions.
The following is the feedback from the customer.
"
...
We observing this issue on x540T interfaces (8086:1528), but not on
82599_SFP (8086:10FB).
...
"
To narrow this problem, I restrict mac.type to ixgbe_mac_X540. I agree
with you. Maybe this problem is
related with the copper phy. But I only have X540 NIC to test. So it is
difficult for me to confirm whether this
problem occurs on other mac type or not, such as X550.
I will consider your suggestions in the latest patch.
Thanks again.
Zhu Yanjun
