    xfrm: Fix xfrm_dev_state_add to fail for unsupported HW SA option · 43024b9c
    Yossef Efraim authored
    xfrm_dev_state_add function returns success for unsupported HW SA options.
    Resulting the calling function to create SW SA without corrlating HW SA.
    Desipte IPSec device offloading option was chosen.
    These not supported HW SA options are hard coded within xfrm_dev_state_add
    function.
    SW backward compatibility will break if we add any of these option as old
    HW will fail with new SW.
    
    This patch changes the behaviour to return -EINVAL in case unsupported
    option is chosen.
    Notifying user application regarding failure and not breaking backward
    compatibility for newly added HW SA options.
