I have a very specific questions about Linux Traffic control and u32 filters in particular. However, I don’t know where the right place is to ask such a question as it’s fairly niche.\n
\n
The [Linux Advanced Routing & Traffic Control](https://lartc.org/) site says it has a mailing list for questions, but the last post was from 2019. There is also the incredibly busy [‘linux-netdev’ mailing list](https://marc.info/?l=linux-netdev), but, the traffic there looks like strictly source changes.\n
\n
Any ideas?\n
\n
**The question I’m trying to find an answer to is:** The u32 tc filter seems to support negative byte offsets which allows you to examine the Ethernet frame header (I don’t think I even found documentation on this, this is thanks to ChatGPT). However, when using u32 values to examine 8 bytes I can only use offsets in increments of 4 - like “at -8” or “at -12”, with any other increment giving me the error `Illegal “match”`.\n
\n
This seems like only a curiosity, but, I’ve been struggling to get my bit-matching to match the way I expect, and I’m wondering if this suggests that matching doesn’t function the way I think.
