P1010-Add MD5 Authentication support in Kernel2.6.35

Hi all,

One of the function of this patch is to add MD5 authentication support in Kernel2.6.35.

Another is when user set a specific IPSEC encryption and authentication, it will display the information through console.

BTW, I'm using P1010RDB for verification.

Share with you guys~
