Re: [PATCH net-next v3] tcp: add rfc3168, section 6.1.1.1. fallback
Please do not top post. My fault. Will be more careful in future. No problem here. I do not see obvious reasons for breaking your setup. It was a problem with my network driver not getting installed due to some symbol mismatch after a compile. It got sorted out after I cleaned up everything. This was a false alarm. Apologies for the noise.

Hi Daniel, With this commit, ifconfig does not show any of the interfaces and I don't have any connectivity as a result. Can you double check this? Thanks!
