Subject: [PATCH net-next 1/2] net: stmmac: Add support for multiple phy interface for integrated PCS
Date: Fri, 24 May 2024 18:36:52 +0530
Message-Id: <20240524130653.30666-2-quic_snehshah@quicinc.com>
In-Reply-To: <20240524130653.30666-1-quic_snehshah@quicinc.com>
References: <20240524130653.30666-1-quic_snehshah@quicinc.com>
Precedence: bulk

In case of integrated PCS ethernet does't have external PCS driver.
Currently stmmac supports multiple phy interfaces if there is external PCS.
Add a function to support mupliple phy interfaces when PCS is integrated.
