/dev/net/ifmgr/ncl

/dev/net/ifmgr/ncl is the IOSU device node that handles network configuration. Its functions are exposed to the Cafe OS userspace through nsysnet.rpl's netconf functions.

ioctl() interface

0x0C - netconf_get_wifi_cfg()

This function is used to get the configuration information of the active wifi profile. It takes no input, and stores its output in a wifi configuration buffer.

0x11 - netconf_set_wifi_cfg()

This function is used to set the configuration information of the active wifi profile. It takes a wifi configuration buffer as input, and produces no output.

0x25 - netconf_set_proxy_cfg()

This function is used to set the configuration information for the proxy of the active wifi profile. It takes a proxy configuration buffer as input, and produces no output.

0x26 - netconf_get_proxy_cfg()

This function is used to get the configuration information for the proxy of the active wifi profile. It takes no input, and stores its output in a proxy configuration buffer.
