commit 5a1e99dd2028e00998d42029be86835d8ef4a46e upstream.
The comparison between traced and symbol addresses is backwards: if
the traced address doesn't exactly match a symbol (which we don't
expect it to), we'll show the next symbol and the offset to it,
whereas we should show the previous symbol and the offset from it.

commit 140c3c6a2bcd2c31e2f7f5a8d59689724776c8e5 upstream.
This works much better if we don't treat protocol numbers as addresses.

A while back I created the dropmonitor protocol, which allowed users to get
reports of dropped frames communicated to them via a netlink socket.
While useful, several people have now asked that I integrate the ability
to do drop monitoring with perf, so they don't have to run additional
tools.
This patch adds a drop monitor script to the perf suite, and provides
the same output that the netlink socket does.
