* Name: up_netinitialize (stub)
|
|
*
|
|
* Description:
|
|
* This is a stub version os up_netinitialize. Normally, up_netinitialize
|
|
* is defined in board/xyz_network.c for board-specific Ethernet
|
|
* implementations, or chip/xyx_ethernet.c for chip-specific Ethernet
|
|
* implementations. The stub version here is used in the corner case where
|
|
* the network is enable yet there is no Ethernet driver to be initialized.
|
|
* In this case, up_initialize will still try to call up_netinitialize()
|
|
* when one does not exist. This corner case would occur if, for example,
|
|
* only a USB network interface is being used or perhaps if a SLIP is
|
|
* being used).
|
|
*
|
|
* Use of this stub is deprecated. The preferred mechanism is to use
|
|
* CONFIG_NETDEV_LATEINIT=y to suppress the call to up_netinitialize() in
|
|
* up_initialize(). Then this stub would not be needed.
