[v2] crypto/qat: fix secure session check
Checks
Commit Message
From: Rebecca Troy <rebecca.troy@intel.com>
Currently when running the dpdk-perf-test with docsis
security sessions, a segmentation fault occurs. This
is due to the check being made that the session is not
equal to op->sym->sec_session. This check passes the
first time but on the second iteration fails and doesn't
create the build_request.
This commit fixes that error by getting the ctx first
from the private session data and then comparing ctx,
rather than op->sym->sec_session, with the sess.
Fixes: fb3b9f492205 ("crypto/qat: rework burst data path")
