Netfilter mark applied to packets after the inbound IPsec SA processed
them. This way it's not necessary to mark packets via Netfilter before
decryption or right afterwards to match policies or process them

Netfilter mark applied to packets after the outbound IPsec SA processed
them. This allows processing ESP packets differently than the original
traffic (e.g. via policy routing).
An additional mask may be appended to the mark, separated by
<literal>/</literal>. The default mask if omitted is 0xffffffff. The

Setting marks in XFRM output is supported since Linux 4.14. Setting a

Whether to copy the DSCP (Differentiated Services Field Codepoint)

<literal>out</literal> only copies the field from the inner to the outer
header, the value <literal>in</literal> does the opposite and only
copies the field from the outer to the inner header when decapsulating,
the value <literal>yes</literal> copies the field in both directions,
and the value <literal>no</literal> disables copying the field
altogether. Setting this to <literal>yes</literal> or

all kernel interfaces.
