Subject: [PATCH 5/9] net/ngbe: fix to read M88E1512 PHY mode
Date: Mon, 30 May 2022 17:30:12 +0800	[thread overview]
Message-ID: <20220530093016.16326-6-jiawenwu@trustnetic.com> (raw)
In-Reply-To: <20220530093016.16326-1-jiawenwu@trustnetic.com>

For M88E1512 PHY mixed mode, PXE driver overrides PHY mode at load
time. To workaround this problem, change to read PHY mode from flash
instead of register.

Fixes: 1c44384fce76 ("net/ngbe: support custom PHY interfaces")
Cc: stable@dpdk.org
