Subject: examples/l2fwd-crypto: check return value on IV size check
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=53b9a5b66d6e2df2e0d92586d6636f03c529ea1a;p=dpdk.git

examples/l2fwd-crypto: check return value on IV size check

IV size parameter is checked through a function,
but its return value was not checked.

Fixes: 0fbd75a99fc9 ("cryptodev: move IV parameters to session")
Fixes: acf8616901b5 ("cryptodev: add auth IV")
Fixes: 2661f4fbe93d ("examples/l2fwd-crypto: add AEAD parameters")
