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 complilation errors Series applied. There were some conflicts I had to resolve due to the recent 64-bit padding fixes, but those weren't too difficult to deal with. Thanks.
