Subject: [net-next PATCH v3 4/4] net: phy: at803x: make read_status more generic
Date: Wed,  3 Jan 2024 13:46:35 +0100
Message-ID: <20240103124637.3078-5-ansuelsmth@gmail.com>

Make read_status more generic in preparation on moving it to shared
library as other PHY Family Driver will have the exact same
implementation.

The only specific part was a check for AR8031/33 if 1000basex was used.
The check is moved to a dedicated function specific for those PHYs.
