Subject: [PATCH] eventdev/eth_rx: fix invalid memory access
Date: Wed, 5 Apr 2023 15:09:59 +0530 [thread overview]
Message-ID: <20230405093959.2052-1-pbhagavatula@marvell.com> (raw)
From: Pavan Nikhilesh <pbhagavatula@marvell.com>
Rx adapter internal service structures are only initialized
when non-internal port is added to the adapter.
Check if Rx adapter service is initialized to determine if
runtime set/get parameters are supported.
Fixes: 3716f52186af ("eventdev/eth_rx: support runtime set/get parameters")
