It looks like it was introduced in 2da489432747 ("octeontx2-pf: devlink params support to set mcam entry count") I will send a new version of the patch with a "Fixes:" tag now.

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.
