[v10,13/18] distributor: check max SIMD bitwidth
Checks
Commit Message
From: Ciara Power <ciara.power@intel.com>
When choosing a vector path to take, an extra condition must be
satisfied to ensure the max SIMD bitwidth allows for the CPU enabled
path.

v4: Updated enum name.
v3: Moved max SIMD bitwidth check to configure function with other vec
support checks.
