From: WingMan Kwok <w-kwok2@xxxxxx>
This patch adds an API to support setting rx mode in
netcp modules. If a netcp module needs to be notified
when upper layer transitions from one rx mode to
another and react accordingly, such a module will implement
the new API set_rx_mode added in this patch. Currently
rx modes supported are PROMISCUOUS and NON_PROMISCUOUS
modes.
