Function Documentation

int __cvmx_helper_sgmii_configure_loopback	(	int	ipd_port,
		int	enable_internal,
		int	enable_external
	)

Configure a port for internal and/or external loopback. Internal loopback causes packets sent by the port to be received by Octeon. External loopback causes packets received from the wire to sent out again.

: IPD/PKO port to loopback. : Non zero if you want internal loopback : Non zero if you want external loopback

Returns Zero on success, negative on failure.

cvmx_helper_link_info_t __cvmx_helper_sgmii_link_get ( int ipd_port )

Return the link state of an IPD/PKO port as returned by auto negotiation. The result of this function may not match Octeon's link config if auto negotiation has changed since the last call to cvmx_helper_link_set().

: IPD/PKO port to query

Returns Link state

int __cvmx_helper_sgmii_link_set	(	int	ipd_port,
		cvmx_helper_link_info_t	link_info
	)

Configure an IPD/PKO port for the specified link state. This function does not influence auto negotiation at the PHY level. The passed link state must always match the link state returned by cvmx_helper_link_get(). It is normally best to use cvmx_helper_link_autoconf() instead.

: IPD/PKO port to configure : The new link state

Returns Zero on success, negative on failure
