[v5,2/2] config/arm: disable SVE ACLE for cn10k
Checks
Commit Message
This disable the sve_acle flag for cn10k.
For native build, -Dplatform=cn10k will require to
get sve_acle flag parameter in the build.
Performance impact:-
With l3fwd example, lpm lookup performance increased
by ~21% if Neon is used instead of SVE. Hence, disabled
sve_acle flag for cn10k.
