Sashiko's comments for v7 arrived late: https://netdev-ai.bots.linux.dev/sashiko/#/patchset/20260924011554.3494-1-sigefriedhyy%40gmail.com
I went through all of them. The only one I will take is the spec doc wording in patch 4: the ifa-index filter and the zero header fields are unconditional for AF_PACKET only, AF_INET and AF_INET6 apply them with NETLINK_GET_STRICT_CHK. I will fix that in v9. The others are either pre-existing, already discussed in earlier versions, or not an issue.
