[dpdk-stable] [PATCH v2 2/5] examples/l2fwd-crypto: skip device not supporting operation

[Pablo de Lara]

When a crypto device does not support an algorithm, it is skipped
and not used. However, when it does support it, but not the rest
of the parameters (IV, key, AAD sizes...), application stops.
Instead, the device should be skipped and the search of a suitable
device should continue.
