# ok 347 407b - Add skbedit action with mark exceeding 32-bit maximum
# not ok 348 d4cd - Add skbedit action with valid mark and mask
# 	Command exited with 255, expected 0
# RTNETLINK answers: Operation not supported
# We have an error talking to the kernel
# 
# not ok 349 baa7 - Add skbedit action with valid mark and 32-bit maximum mask

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.
