Subject: [dpdk-dev] [PATCH V2 07/10] net/bnxt: fix a memory leak in port stop
Date: Mon, 13 Jan 2020 10:31:15 +0530	[thread overview]
Message-ID: <20200113050118.28719-8-kalesh-anakkur.purayil@broadcom.com> (raw)
In-Reply-To: <20200113050118.28719-1-kalesh-anakkur.purayil@broadcom.com>

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

The memory for mark table is allocated during port start.
But the allocated memory is freed only during port close
or driver unload which in turn causes a memory leakage
on each port start/stop.

Fixed it by moving the memory free to port stop.

Fixes: a968a9f5456d ("net/bnxt: add support for flow mark action")
