Series Acked-by: Jerin Jacob <jer...@marvell.com> Series Tested-by: Jerin Jacob <jer...@marvell.com> # Verified the mcpu and cache line aspects of generic an octeontx2 build # Test the performance of build. No regression see with testpmd, l2fwd, and l3fwd, I would suggest merging this for RC4. Additional features/enhancements can be done in 21.02 for release.
