Subject: [PATCH 4.14 13/60] net/mlx4_core: Fix init_hca fields offset
Date: Mon, 23 Nov 2020 13:21:55 +0100 [thread overview]
Message-ID: <20201123121805.680574374@linuxfoundation.org> (raw)
In-Reply-To: <20201123121805.028396732@linuxfoundation.org>
From: Aya Levin <ayal@nvidia.com>
[ Upstream commit 6d9c8d15af0ef20a66a0b432cac0d08319920602 ]
Slave function read the following capabilities from the wrong offset:
1. log_mc_entry_sz
2. fs_log_entry_sz
3. log_mc_hash_sz
Fix that by adjusting these capabilities offset to match firmware
layout.
Due to the wrong offset read, the following issues might occur:
1+2. Negative value reported at max_mcast_qp_attach.
3. Driver to init FW with multicast hash size of zero.
Fixes: a40ded604365 ("net/mlx4_core: Add masking for a few queries on HCA caps")
