#Apple thunderbolt ethernet adapter mac address changing windows 10

Please note that if I boot in Windows 10 with the same HW (Intel NUC) and physical configuration (SL2 via TB3 to TB2), the Intel X540 contained in the Promise SANLink2 10GbE via the Thunderbolt bus works perfectly fine:.

(B) an Apple Thunderbolt3 to Thunderbolt2 adapter is not officially part of the HCL (A) the Intel NUC is not officially part of the HCL (many people in the community use NUCs for home labs)

The problem isn't the SANLink2 10GbE (Intel X540) but an MMIO addressing issue amongst the Thunderbolt bus translation to ESXi when using a TB3 to TB2 adapter hence, the ixgben driver never gets assigned.The problem would have made more sense if the PCI card didn't get detected by ESXi however, the fact that it is detected, ESXi should be able to assign the ixgben driver.Name PCI Device Driver Admin Status Link Status Speed Duplex MAC Address MTU Description It appears that ESXi fails to address the Intel X540 with the ixgben driver when the TB3 to TB2 adapter is the intermediary between the host and esxcli network nic list In addition, I have an Apple Thunderbolt to Gigabit Ethernet Adapter (Broadcom Corporation NetXtreme BCM57762) connected via the same Thunderbolt chain and the network port get detected with the tg3 inbox driver.You can clearly see that the ESXi detects the PCI card however, there seems to be some addressing issue on the PCI side of things as it fails to list the (2) available network ports.

On ESXi, the Intel X540 PCI card does get detected and is properly listed under Hardware -> PCI lspci | grep X540Ġ000:40:00.0 Ethernet controller: Intel(R) Ethernet Controller 10 Gigabit X540-AT2Ġ000:40:00.1 Ethernet controller: Intel(R) Ethernet Controller 10 Gigabit X540-AT2.Connected to the Intel NUC via an Apple Thunderbolt3 to Thunderbolt2 AdapterĮSXi fails to list the Intel X540 ( ixgben) as configurable network ports via a Thunderbolt3 to Thunderbolt2 Apple Adapter.Uses the Intel X540 AT2 Ethernet Controller.
