commit: f473122f41f69394e29a834fbfcd569dcdd1d879 [24/25] RDMA/irdma: Add irdma Kconfig/Makefile and remove i40iw
config: parisc-allyesconfig (attached as .config)
compiler: hppa-linux-gcc (GCC) 9.3.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
