commit: 6aa942ad90fae85c4ad0aa9434ffdfac170cb7da [7/15] net/mlx5: Add sample offload hardware bits and structures
config: mips-randconfig-r032-20201014 (attached as .config)
compiler: mips-linux-gcc (GCC) 9.3.0
reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# https://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux.git/commit/?id=6aa942ad90fae85c4ad0aa9434ffdfac170cb7da
git remote add saeed https://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux.git
git fetch --no-tags saeed net-next-mlx5
git checkout 6aa942ad90fae85c4ad0aa9434ffdfac170cb7da
# save the attached .config to linux build tree
