Subject: [net 3/5] net/mlx5: Fix PPLM register mapping
Date: Tue,  6 Apr 2021 21:06:18 -0700	[thread overview]
Message-ID: <20210407040620.96841-4-saeed@kernel.org> (raw)
In-Reply-To: <20210407040620.96841-1-saeed@kernel.org>

From: Aya Levin <ayal@nvidia.com>

Add reserved mapping to cover all the register in order to avoid
setting arbitrary values to newer FW which implements the reserved
fields.

Fixes: a58837f52d43 ("net/mlx5e: Expose FEC feilds and related capability bit")
