Dsegmentation-offloads.rst69 contain additional headers such as an outer tunnel. In order to account
73 cases where there are more than just 1 set of headers. For example in the
74 case of IPIP and SIT we should have the network and transport headers moved
75 from the standard list of headers to "inner" header offsets.
77 Currently only two levels of headers are supported. The convention is to
78 refer to the tunnel headers as the outer headers, while the encapsulated
79 data is normally referred to as the inner headers. Below is the list of
