Subject: [net-next PATCH v4 12/13] net: netcp: add api to support set rx mode in netcp modules
Date: Tue, 17 Apr 2018 17:30:41 -0400	[thread overview]
Message-ID: <1524000642-23944-13-git-send-email-m-karicheri2@ti.com> (raw)
In-Reply-To: <1524000642-23944-1-git-send-email-m-karicheri2@ti.com>

From: WingMan Kwok <w-kwok2@ti.com>

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.
