Hi!
I'm sol sorry, but English in not my native language.
After upgrade kernel tc lost some u32 filters
example: where is a "match ip dst 10.10.0.0/24" entries?
[root@sol ~]# tc -b tc.batch
[root@sol ~]# tc filter list dev p10p1

If i copy-paste pules directly to tc command line, tc accept this line
without any error. But rule in tc filter show is absent.
