Subject: Re: [PATCH net-next v2 00/10] drop_monitor: Capture dropped
 packets and metadata

> So far drop monitor supported only one mode of operation in which a
> summary of recent packet drops is periodically sent to user space as a
> netlink event. The event only includes the drop location (program
> counter) and number of drops in the last interval.
> 
> While this mode of operation allows one to understand if the system is
> dropping packets, it is not sufficient if a more detailed analysis is
> required. Both the packet itself and related metadata are missing.
> 
> This patchset extends drop monitor with another mode of operation where
> the packet - potentially truncated - and metadata (e.g., drop location,
> timestamp, netdev) are sent to user space as a netlink event. Thanks to
> the extensible nature of netlink, more metadata can be added in the
> future.
