 Limitations
 -----------
 
-* Chained mbufs are not supported.
 * Hash only is not supported except SNOW 3G UIA2 and KASUMI F9.
-* Cipher only is not supported except SNOW 3G UEA2 and KASUMI F8.
 * Only supports the session-oriented API implementation (session-less APIs are not supported).
-* Not performance tuned.
 * SNOW 3G (UEA2) and KASUMI (F8) supported only if cipher length, cipher offset fields are byte-aligned.
 * SNOW 3G (UIA2) and KASUMI (F9) supported only if hash length, hash offset fields are byte-aligned.
 * No BSD support as BSD QAT kernel driver not available.
