Thanks Hans and Julian.
I did the following and still see the problem
#cd /usr/src
#make buildworld WITH_OFED=yes
#make installworld WITH_OFED=yes
#reboot
#cd /usr/src
#make buildkernel WITH_OFED=yes KERNCONF=MYKERNEL ; MYKERNEL content is shown below in case it is a cause
#make installkernel WITH_OFED=yes KERNCONF=MYKERNEL
#reboot
#cd /usr/src/sys/modules/linuxkpi
#make clean && make WITH_OFED=yes
#cd /usr/src/sys/modules/ibcore
#make clean && make WITH_OFED=yes
#kldload -v /usr/obj/usr/src/amd64.amd64/sys/modules/linuxkpi/linuxkpi.ko
#kldload -v /usr/obj/usr/src/amd64.amd64/sys/modules/ibcore/ibcore.ko
linuxkpi.ko loads fine.
However I see the same error when I load ibcore.ko
================
link_elf_obj: symbol if_index undefined
linker_load_file: /usr/obj/usr/src/amd64.amd64/sys/modules/ibcore/ibcore.ko - unsupported file type
================
I don't see any such problems with FreeBSD11.1 or 11.0 Kernels.
Would appreciate any help.
Cheers

If you build outside the "buildkernel WITH_OFED=YES" target these flags must be specified manually in my experience.
