Hi Manjae,

may be this is version v2 of this patch with this subject. But the 
version is not about the subject. It is about the code change itself.

So I can see that this patch was send in with the following subjects:
[PATCH] Improve MAR register definition and usage for rtl8723
[PATCH v2] staging: rtl8723bs: Improve MAR register definition and usage
[PATCH] staging: rtl8723bs: Improve MAR register definition and usage
[PATCH v2] staging: rtl8723bs: Improve clarity of MAR usage

To me the last patch should be a v4. The next patch you send is the v5.
A change history is expected.

Thanks for your support.
