[dpdk-stable] [PATCH 4/5] doc: remove incorrect limitation on QAT PMD

[Pablo de Lara]

[ backported from upstream commit de938b79b2fce7e15389aad1543e778a8721e3a5 ]

QAT supports authentication only operations,
for any authentication algorithm (such as SHA1-HMAC),
as long as it is supported by QAT, so it means
that it is not necessary to create a chained operation
in order to use these algorithms.

Fixes: 1703e94ac5ce ("qat: add driver for QuickAssist devices")
