2022-06-29classify: use 32 bits hashBenoît Ganne1-5/+4
classify hash used to be stored as u64 in buffer metadata, use 32 bits instead: - on almost all our supported arch (x86 and arm64) we use crc32c intrinsics to compute the final hash: we really get a 32-bits hash - the hash itself is used to compute a 32-bits bucket index by masking upper bits: we always discard the higher 32-bits - this allows to increase the l2 classify buffer metadata padding such as it does not overlap with the ip fib_index metadata anymore. This overlap is an issue when using the 'set metadata' action in the ip ACL node which updates both fields Type: fix Change-Id: I5d35bdae97b96c3cae534e859b63950fb500ff50 Signed-off-by: Benoît Ganne <bganne@cisco.com>

2018-03-11vnet: l2-classify: prefetch (n+2, n+3) rather than (n+1, n+2) inside dual ↵Andrew Yourtchenko1-5/+5
loop code The dual loop within the L2 classifier processes the (n, n+1) packets, the prefetching was trying to prefetch (n+1, n+2) - thus half of the prefetches were not used - because the next iteration needs (n+2, n+3).

2017-07-23Improve L2 Input/Output Feature Infrastructure and UsageJohn Lo1-15/+7
Simplify L2 output feature infra to unify with L2 input feature infra using the newly improved feature bitmap mechanism. Updated all L2 features to use the more efficient infra functions. Change-Id: If8f463826b0af0717129befe92a27ea8cfc40449 Signed-off-by: John Lo <loj@cisco.com>
