Subject: [dpdk-dev] [PATCH 08/17] net/bnxt: cleanup vnic after flow validate
Date: Mon,  2 Sep 2019 19:18:52 -0700	[thread overview]
Message-ID: <20190903021901.25895-9-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20190903021901.25895-1-ajit.khaparde@broadcom.com>

When an application issues flow validate, we free the temporary
filter that is created. But the vnic is not freed up. This can
potentially interfere with subsequent flow creation. So free the vnic.
