Subject: net/iavf: reset security context pointer on stop
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=23abab4f14d3e2425e74c296769d21b79d696096;p=dpdk.git

net/iavf: reset security context pointer on stop

When iavf_security_ctx_destroy() is cleaning up, it does not correctly
set the security_ctx variable to NULL, which will lead to wild pointer.

Fixes: 6bc987ecb860 ("net/iavf: support IPsec inline crypto")
