Message-Id: <20210531151403.12494-2-ogabbay@kernel.org>
Date: Mon, 31 May 2021 18:13:59 +0300
From: Oded Gabbay <ogabbay@...nel.org>
To: linux-kernel@...r.kernel.org
Subject: [PATCH 2/6] habanalabs/gaudi: don't use nic_ports_mask in compute
nic_ports_mask is used by the networking part of the driver.
In the compute part, we use the HW_CAP bits to select what is active
and what is not.
