Subject: [PATCH] app/testpmd: fix copy of raw flow item
[ upstream commit 67af7ecc52ec0abdec3e9d5b35dcd4dc78b595ce ]
When calculate memory size of an RTE_FLOW_ITEM_TYPE_RAW 's mask
mask->length is not the real size of binary pattern, it should take
spec->length, or memory size will be over counted (0xffff) and invalid
memory be access during following memcpy.
Fixes: d0ad8648b1c5 ("app/testpmd: fix RSS flow action configuration")
