From cd565b4b51e5fe258d6ce9ddc167ee51f3044ba5 Mon Sep 17 00:00:00 2001 From: Erez Shitrit Date: Mon, 10 Apr 2017 11:22:30 +0300 Subject: [PATCH] IB/IPoIB: Support acceleration options callbacks IPoIB driver now uses the new set of callback functions. If the hardware provider supports the new ipoib_options implementation, the driver uses the callbacks in its data path flows, otherwise it uses the driver default implementation for all data flows in its code. The default implementation wasn't change and it is exactly as it was before introduction of acceleration support.
