How to track memory usage of the networking subsystem in the Linux kernel?

Is there a way to determine how much physical memory is being used by the network subsystem in the Linux kernel at any given point in time? I understand the per-connection memory limits can be specified via sysctl. But is there a tool to peek inside the TCP/IP stack and ask it how much buffered data it has per connection?

Did you try: ss -m? The documentation of the reported values seems scarce but you can make educated guesses based on their full names defined in linux/sock_diag.h.
