Subject: TCP_REPAIR MSS issue

Hi,

I see an issue with TCP_REPAIR on kernel 4.6.0, where a migrated connection is only sending minimum-sized segments (~500 bytes), although the interfaces and path support Ethernet-sized MTUs. A connection that doesn't use TCP_REPAIR over the same path uses full-sized segments.

Know issue? Any workaround?

Thanks,
Lars
