Rick Jones fb811395cd net: add explicit logging and stat for neighbour table overflow ... Add an explicit neighbour table overflow message (ratelimited) and statistic to make diagnosing neighbour table overflows tractable in the wild. Diagnosing a neighbour table overflow can be quite difficult in the wild because there is no explicit dmesg logged. Callers to neighbour code seem to use net_dbg_ratelimit when the neighbour call fails which means the "base message" is not emitted and the callback suppressed messages from the ratelimiting can end-up juxtaposed with unrelated messages. Further, a forced garbage collection will increment a stat on each call whether it was successful in freeing-up a table entry or not, so that statistic is only a hint. So, add a net_info_ratelimited message and explicit statistic to the neighbour code. Signed-off-by: Rick Jones <rick.jones2@hp.com> Signed-off-by: David S.
