(please be noted we reported
"[printk]  8e27473211: hwsim.ap_ft_pmf_bip_gmac_256.fail"
on
https://lore.kernel.org/all/20220430143056.GA27004@xsang-OptiPlex-9020/
when this commit is on linux-next/master
now we noticed there are other hwsim tests failures while
ap_ft_pmf_bip_gmac_256 problem is still existing, after this commit is on
mainline now.

To reproduce:

        git clone https://github.com/intel/lkp-tests.git
        cd lkp-tests
        sudo bin/lkp install job.yaml           # job file is attached in this email
        bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
        sudo bin/lkp run generated-yaml-file

        # if come across any failure that blocks the test,
        # please remove ~/.lkp and /lkp dir to run from a clean state.
