[Liu, Mingxia] how about use the macro variable ?
#define CPFL_REPRESENTOR_ID(type, host_id, pf_id, vf_id)\
((((type) & 0x3) << 14) + (((host_id) & 0x1) << 13) + (((pf_id) & 0x1) << 12)
+ ((vf_id) & 0xfff))

[Liu, Mingxia] For good readability, func_type value 0 and 1 are better to be
replaced by macro variables.
