Added cipher-only, hash-only operation cases,
which will be supported in the future.
Also, only sets authentication and ciphering parameters
when needed.

To: dev
Crypto devices now have information about
which crypto operations they are capable of provide.
This patch makes the app use this information,
removing all hardcoded values.
User now needs to create the virtual crypto devices
or bind the HW crypto devices, and the app will use
the ones capable of performing the crypto op specified
(user can select between HW/SW through command line)

Subject: [dpdk-dev] [PATCH 0/6] L2fwd-crypto enhancements
This patchset cleans up the l2fwd-crypto app, implements some missing functionality and makes use of the new capability discovery mechanism that cryptodev library offers to discover which crypto operations a PMD can provide.
This patchset depends on "cryptodev: add capabilities discovery mechanism" patch
(http://dpdk.org/dev/patchwork/patch/11434/)
Pablo de Lara (6):
l2fwd-crypto: code cleanup
l2fwd-crypto: update auth algo list
l2fwd-crypto: implement parse_key function
l2fwd_crypto: add AAD parsing
l2fwd-crypto: add missing cipher/hash only cases
l2fwd-crypto: use cryptodev capability discovery
