[PATCH v2 net-next 5/8] net: phy: Add helper for advertise to lcl value
From: Andrew Lunn <andrew@lunn.ch>
Date: 2018-09-30 03:36:57
Subsystem:
amd xgbe driver, ethernet phy library, freescale etsec ethernet driver (gianfar), hisilicon network subsystem 3 driver (hns3), hisilicon network subsystem driver, mediatek ethernet driver, mediatek switch driver, networking drivers, networking [dsa], socionext (sni) ave network driver, the rest · Maintainers:
Raju Rangoju, Prashanth Kumar K R, Andrew Lunn, Heiner Kallweit, Claudiu Manoil, Jian Shen, Jijie Shao, Felix Fietkau, Lorenzo Bianconi, Chester A. Unal, Daniel Golle, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Vladimir Oltean, Kunihiko Hayashi, Linus Torvalds
Add a helper to convert the local advertising to an LCL capabilities, which is then used to resolve pause flow control settings.
