Hi Gregory,
Can you please give more details why 'id' needs to be 64 bits, with
callstack or usecase etc?
And please describe what is the observed problem with current code?
Inside 'parse_indlst_id2ptr()',
'parse_int()' can work or 32bits and 64bits variables, so that one is OK.
But both 'port_action_handle_get_by_id()' &
'indirect_action_list_conf_get()' gets 'id' as parameter and they get
32bits argument, when 'id' is 64bit won't it will be cast to 32bits and
loose data, should those functions needs to be updated as well.
