From 0542a87c546726510e7a572b16c5493ca42024c4 Mon Sep 17 00:00:00 2001 From: WingMan Kwok Date: Tue, 17 Apr 2018 17:30:41 -0400 Subject: [PATCH] net: netcp: add api to support set rx mode in netcp modules 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. Signed-off-by: WingMan Kwok Signed-off-by: Murali Karicheri Signed-off-by: David S.
