Since act_simple is an academic example:
I think that a better solution is to add TCA_DEF_DATA (which is a
string) to the nla_policy. nla_policy is defined but at the moment it is
not used in the call to nla_parse_nested() - might as well use it.
Roel, would you like to take a crack at that? You will need to define
the max size of the string that TCA_DEF_DATA can hold (if you want to do
it cleanly then define it in include/linux/tc_act/tc_defact.h). This MAX
size will appear in the nla_policy.
cheers,
jamal
