Please note we do not allocate a big buffer, only allow more small skbs
to be queued on socket receive queue.
If memory is not available, skb allocation will eventually fail
and be reported as well, embedded or not.
I vote for allowing 1024*1024 bytes instead of 32768,
and eventually user should be warned that it is capped by
/proc/sys/net/core/rmem_max

Yes, but caller of 'ip monitor' just restart it anyway
