Hi, I would like to determine through which interface packets sent to a particular UDP destination will go through, and so determine the MTU size for that interface. Can anyone suggest a good way of doing this from within the kernel?
Doing this will permit AF_RXRPC to obtain a better initial guess as to the maximum size of the packets that can be sent that way. I could use the code Patrick gave me to allow AFS to iterate through all the interfaces and then pick the smallest MTU, but that seems wrong somehow - though it probably will result in the correct answer 99% of the time.
