Subject: bnxt_en fails to initialize MAC address in Oracle cloud

We got a bug report against Ubuntu about networking failing to come up
in the Oracle cloud:

https://bugs.launchpad.net/bugs/1790652

This is with a kernel based on 4.18.5, and it has also been seen with a
4.17-based kernel. I'm not currently aware of any working kernel
version. The driver seems to be getting an error response from the
firmware when trying to set the MAC address.

[    2.437420] Broadcom NetXtreme-C/E driver bnxt_en v1.9.1
[    2.449820] bnxt_en 0000:00:03.0 (unnamed net_device) (uninitialized): hwrm req_type 0xf seq id 0x5 error 0xffff
[    2.455610] bnxt_en 0000:00:03.0 (unnamed net_device) (uninitialized): VF MAC address 00:00:17:02:05:d0 not approved by the PF
[    2.461443] bnxt_en 0000:00:03.0: Unable to initialize mac address.
[    2.483531] bnxt_en: probe of 0000:00:03.0 failed with error -99

Let me know if there's more information you need, and we'll try to get
it for you.

Thanks,
Seth
