# phy\_start\_aneg(9)

start auto-negotiation for this PHY device

## NAME

phy\_start\_aneg - start auto-negotiation for this PHY device

## SYNOPSIS

**int phy\_start\_aneg(struct phy\_device \*** *phydev***);**

## ARGUMENTS

*phydev*

the phy\_device struct

## DESCRIPTION

Sanitizes the settings (if we're not autonegotiating them), and then calls the driver's config\_aneg function. If the PHYCONTROL Layer is operating, we change the state to reflect the beginning of Auto-negotiation or forcing.
