Subject: [PATCH v1 1/2] net: stmmac: mmc_core: Add GMAC LPI statistics
Date: Mon,  1 Apr 2024 10:44:55 +0800	[thread overview]
Message-ID: <20240401024456.41433-1-minda.chen@starfivetech.com> (raw)

XGMAC MMC has already added LPI statistics. GMAC MMC lack of these
statistics. Add register definition and reading the LPI statistics
from registers.
