Retrieving Adapter Card GUID
On ConnectX-3 Ethernet adapter cards, there is a mismatch between the GUID value returned by
firmware management tools and that returned by fabric/driver utilities that read the GUID via
device firmware (e.g., using ibstat). Mlxburn/flint returns 0xffff as GUID while the utilities return
a value derived from the MAC address. For all driver/firmware/software purposes, the latter value
should be used. Please see the below example.
Note: The shown versions and/or parameter values in the example below may not reflect the lat-
est or actual values for this product, and are included here for illustration purposes only.
