Commit Message

Brian Dooley June 5, 2024, 8:53 a.m. UTC
  Currently IPsec MB provides both the JOB API and direct API.
AESNI_MB PMD is using the JOB API codepath while KASUMI and
CHACHA20_POLY1305 are using the direct API.
Instead of using the direct API for these PMDs, they should now make
use of the JOB API codepath. This would remove all use of the IPsec MB
direct API for these PMDs.
