Hi Vlad,
I have gone through this mail chain and followed the instructions specified. I
have cloned all three repos, exported those environment variables and run
admin_rdma.sh script to get the ofa_kernel tree.
After this i configured the ofa_kernel with --with-cxgb3 --with-cxgb4 options.
Then executed make command and ended up in above build failure.
Thanks,
Vipul
