Subject: [PATCH net-next 1/1] net sched qdisc: pass netlink message flags in event notification

Userland client should be able to read an event, and reflect it back to
the kernel, therefore it needs to extract complete set of netlink flags.
    
For example, this will allow "tc monitor" to distinguish Add and Replace
qdisc operations.
