Re: [patch] ipvs: off by one in set_sctp_state()

[Moahn Reddy <mohanreddykv@gmail.com>]

Hi,

I see there is no problem in the code regarding the state change. And 
the thing why I took 255 in the sctp_events array is that as per the 
sctp specification, the 255 message is reserved, so I thought 0 to 254 
messages are enough.

Do you see any problem with the ipvs sctp code in the field?. Please let 
me know if you see any such, I will try to fix.

Thanks,
Mohan
