Re: [ovs-discuss] Error in "Make" after patching OVS

2018-04-03 Thread Mark Michelson 
This is because you altered an enum, which resulted in the 
OVS_KEY_ATTR_TUNNEL_INFO value changing. You need to adjust the 
BUILD_BUG_ON statement referenced in the error message to compare to the 
new value instead.


I don't mean to be rude, but the questions you have been asking on this 
list have been pretty basic. I feel like you could have figured out the 
answers by doing some local debugging or using your search engine of 
choice. I recommend that you take more time to try to learn the answers 
on your own before mailing the list next time. You'll learn more by 
doing it that way.
