Pasha, network buffers fields are not the only fields which are actual in /proc/user_beancounters in Virtuozzo 7 kernel,
so please
1) for "old" Containers (created and managed using ioctls with CTID - int) - make network-related parameters in /proc/user_beancounters show actual info
   or just some dummy values, and put info about which values are "real" into the jira issue: https://jira.sw.ru/browse/PSBM-33584

2) for "new" Containers (new cgroup-based interface): for each parameter from /proc/user_beancounters please post where its value can be taken (via croups interface).
   And post the info into https://jira.sw.ru/browse/PSBM-33584 as well.

Thank you.
