H A D | inetpeer.h | diff ddd4aa424b866a08ceba7ddf38e61542c91b93a0 Thu Feb 10 00:36:47 CET 2011 David S. Miller <davem@davemloft.net> inetpeer: Add redirect and PMTU discovery cached info.
Validity of the cached PMTU information is indicated by it's expiration value being non-zero, just as per dst->expires.
The scheme we will use is that we will remember the pre-ICMP value held in the metrics or route entry, and then at expiration time we will restore that value.
In this way PMTU expiration does not kill off the cached route as is done currently.
Redirect information is permanent, or at least until another redirect is received.
