Summary: One minor issue to discuss
Major issues: none
As can be seen, the WESP format extends the standard ESP header
by the first 4 octets for IPv4 and by 8 octets for IPv6. The
WESP header is integrity protected, along with all the fields
specified for ESP in RFC 4303.
Normally ESP wouldn't need to process encapsulation headers that appear prior to the SPI. Won't this require modification of the ESP implementation, possibly breaking its modularity? Would it be problematic for certain algorithms to include this data? It might be good to state that.
Nits/editorial comments: none
