[ns] Help with ns2.33 patch to support mobile ipv6

[Oladapo Oluwadiya]

hello,

i found patches for ns2.33 to support mobile ipv6 on this link http://nicta.com.au/people/mehanio/nsmisc 
i am not sure which of the two patches i need to install because there are two of them relating to ns2.33 mobiwan i.e. ns-233-mobiwan-1.patch and ns-233-mobiwan-rfc3775-1.patch.
i m using ns2.33 with cygwin 1.5.25-15.
the second question is how do i install the patch?
regards
