Just adding my own experiences, sry for the necro, maybe useful for someone else... port flapping  With the same X520-DA2 combined with mikrotik S+AO00005 cable to a Mikrotik CRS305-1G-4S+IN used as a switch

Jan 28 21:54:04 Storage kernel: bond0: link status definitely down for interface eth0, disabling it
Jan 28 21:54:53 Storage kernel: ixgbe 0000:65:00.0 eth0: NIC Link is Up 10 Gbps, Flow Control: RX/TX
Jan 28 21:54:53 Storage kernel: bond0: link status definitely up for interface eth0, 10000 Mbps full duplex
Jan 28 21:54:55 Storage kernel: ixgbe 0000:65:00.0 eth0: NIC Link is Down
Jan 28 21:54:55 Storage kernel: bond0: link status definitely down for interface eth0, disabling it

Port flapping occured in one of the ports, the other I think just didn't log it, as it sure wasn't working, and while the switch showed link, unraid reported it as down.

 

fw version:

 

# ethtool -i eth0
driver: ixgbe
version: 5.3.6
firmware-version: 0x80000231
expansion-rom-version:
bus-info: 0000:65:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes

 

 

Exhibited the same problem in another PC, (old Z79 based) but not in a third (Z99). The unRaid one is a X299 based newer machine. Very weird compatibility issue.
