The primary addition is support checksum neutral ILA translation. This allows address to be performed and still keep any transport layer checksums that include the addresses in their pseudo header to still be correct without the translator needing to parse L4. Other items are: - Structures for ILA addresses, identifiers, locators - Disallow translation on non-ILA addresses (check by type in identifier). - Change xlat (nf_input) to translates solely based on matching locators not identifiers (since identifiers are not obfuscated by checksum neutral). - Side effect if above is that multiple ILA domains are supported. Each local locator can map to a different SIR address (ILA domain), and each domain defines its own identifier space. Tested: Ran TCP_RR with 200 cnxs. ILA performance is slightly better than previously since we are not longer parsing L4 for checksum handling. I amd seeing about 1% performance overhead. Also ran TCP_STREAM and tested non-ILA address (type=0) are not translated. v2: Fix compilation errors ==================== Signed-off-by: David S. Miller --- fab7b629a82da1b59620470d13152aff975239f6
