+Subject: [PATCH] netsniff-ng: nlmsg: Drop dissection of GENL_ID_GENERATE type
+
+After kernel commit a07ea4d9941a ("genetlink: no longer support using
+static family IDs"), GENL_ID_GENERATE is no longer exposed to userspace
+(and actually should never have been). Change the genl nlmsg dissector
+to only consider the nlctrl family and the two other static family IDs
+needed for workarounds. All other family IDs are considered dynamically
+generated.
+
+Fixes #171
