When using COMPILE_TEST, the driver controlled by OCTEONTX2_PF does
not select NET_DEVLINK while the related OCTEONTX2_AF driver does.
This means that when OCTEONTX2_PF is enabled from a default
configuration, linker errors will occur due to undefined references to
code controlled by NET_DEVLINK.
1. make.cross ARCH=x86_64 defconfig
2. make.cross ARCH=x86_64 menuconfig
3. Enable COMPILE_TEST
General setup --->
Compile also drivers which will not load
4. Enable OCTEONTX2_PF
Device Drivers --->
Network device support --->
Ethernet driver support --->
Marvell OcteonTX2 NIC Physical Function driver
5. Exit and save configuration. NET_DEVLINK will still be disabled.
6. make.cross ARCH=x86_64 several linker errors, for example,
ld: drivers/net/ethernet/marvell/octeontx2/nic/otx2_devlink.o:
in function `otx2_register_dl':
otx2_devlink.c:(.text+0x142): undefined reference to `devlink_alloc_ns'
This fix adds "select NET_DEVLINK" link to OCTEONTX2_PF's Kconfig
specification to match OCTEONTX2_AF.

This has been fixed a long time ago by 9cbc3367968d ("octeontx2-pf:
select CONFIG_NET_DEVLINK") no?

You are right. My apologies. I was looking at an older kernel.
