The options control whether the DF and ECN header bits/fields are copied
from the unencrypted packets to the encrypted packets in tunnel mode (DF only
for IPv4), and for ECN whether the same is done for inbound packets.
Note: This implementation only works with Linux/Netlink/XFRM.
Based on a patch by Markus Sattler.
Use argument evaluation provided by settings_t instead of using strings
to enumerate key/values.
If section names contain dots the latter causes the names to get split
and interpreted as non-existing sections and subsections.
This currently doesn't work for connections and their subsections due to
the recursion.
When requiring unique flags for CHILD_SAs, allow the configuration to
request different marks for each direction by using the %unique-dir keyword.
This is useful when different marks are desired for each direction but the
number of peers is not predefined.
An example use case is when implementing a site-to-site route-based VPN
without VTI devices.
A use of 0.0.0.0/0 - 0.0.0.0/0 traffic selectors with identical in/out marks
results in outbound traffic being wrongfully matched against the 'fwd'
policy - for which the underlay 'template' does not match - and dropped.
Using different marks for each direction avoids this issue as the 'fwd' policy
uses the 'in' mark will not match outbound traffic.

There was a direct call to load_key() for unencrypted keys that didn't
remove the key ID from the hashtable, which caused keys to get unloaded
when --load-creds was called multiple times.
The original name is returned in the new "name" attribute.
This fixes an issue with bindings that map VICI messages to
dictionaries. For instance, in roadwarrior scenarios where every
CHILD_SA has the same name only the information of the last CHILD_SA
would end up in the dictionary for that name.
When fresh CRLs are released with a high update frequency (e.g.
every 24 hours) or OCSP is used then the certificate cache gets
quickly filled with stale CRLs or OCSP responses. The new VICI
flush-certs command allows to flush e.g. cached CRLs or OCSP
responses only. Without the type argument all kind of certificates
(e.g. also received end entity and intermediate CA certificates)
are purged.
