rndis_host: Add early_init function pointer to 'struct rndis_data'. (7c39e038) · Commits · 戴 / test

Function pointer is for 'subminidrivers' that need to do work on device right after minidriver has initialized hardware. For example, rndis_wlan setting device specific configuration parameters with OID_GEN_RNDIS_CONFIG_PARAMETER right after rndis_host has initialized hardware with RNDIS_INIT. Signed-off-by:
