I found my problem. Turned out I didn't have the QOS fwmark routing flag enabled in the kernel for that host. Those RTNETLINK errors are so useless. I wish this was documented in that section of the LARTC howto. I looked for where to submit that as a suggestion and just see 20 different authors listed. Documenting the required kernel settings for match u32, fwmark, etc. where they are each discussed would seem like a useful thing. BTW, w1g1 is a sangoma wanpipe T1.
