[dpdk-stable] [PATCH 1/5] crypto/qat: fix HMAC supported key sizes

[Pablo de Lara]

[ backported from upstream commit 5668da1eb5897a96b672ac3b610bd3542e3e5cbe ]

For HMAC algorithms (MD5-HMAC, SHAx-HMAC), the supported
key sizes are not a fixed value, but a range between
1 and the block size.

Fixes: 26c2e4ad5ad4 ("cryptodev: add capabilities discovery")
