From 2f6373245a09e2a34f36df7d982f783291ec8fce Mon Sep 17 00:00:00 2001 From: Satish Ashok Date: Mon, 26 Jan 2015 01:17:00 -0500 Subject: [PATCH] bonding: fix LACP PDU not sent on slave port sometimes When a slave is added to a bond and it is not in full duplex mode, AD_PORT_LACP_ENABLED flag is cleared, due to this LACP PDU is not sent on slave. When the duplex is changed to full, the flag needs to be set to send LACP PDU.
