From 4f1e87a332877fd606883585ae03e23526ba9a85 Mon Sep 17 00:00:00 2001 From: Jia Yu Date: Thu, 27 Nov 2014 21:23:37 +0000 Subject: [PATCH] bond: set offload capabilities flags Before the fix, bond device's offload capabilities are unset. This fix takes the minimum common set of slave devices' capabilities as bond device's capabilities. For simplicity, we ensure all slave devices to have a capability before bond device can claim this capability, even if some slave devices are unused (i.e. linked down, standby).
