Subject: [dpdk-stable] [PATCH 18.11 1/5] net/bnxt: fix structure variable initialization
Date: Tue,  1 Dec 2020 09:09:26 +0530
Message-ID: <20201201033930.17869-2-kalesh-anakkur.purayil@broadcom.com> (raw)
In-Reply-To: <20201201033930.17869-1-kalesh-anakkur.purayil@broadcom.com>

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

[ upstream commit ce41561d1b998d9e15f74f9c3a6aff78e0f99871 ]

During port start if bnxt_alloc_all_hwrm_stat_ctxs() fails,
in the cleanup path we do see errors like below:

bnxt_hwrm_ring_free(): hwrm_ring_free cp failed. rc:2
bnxt_hwrm_ring_free(): hwrm_ring_free rx failed. rc:2

The reason for this is in bnxt_free_all_hwrm_rings(), the check
is made against "ring->fw_ring_id != INVALID_HW_RING_ID" which
always return true as ring->fw_ring_id is not set to INVALID_HW_RING_ID
while initialising the ring structs.

Fixes: 6eb3cc2294fd ("net/bnxt: add initial Tx code")
Fixes: 2eb53b134aae ("net/bnxt: add initial Rx code")
