From eb14032f9eb595621270f3269f40094adb3144e8 Mon Sep 17 00:00:00 2001 From: Eli Cohen <eli@mellanox.co.il> Date: Wed, 30 Jan 2008 18:30:46 +0200 Subject: [PATCH] IPoIB: Add high DMA feature flag All current InfiniBand devices can handle all DMA addresses, and it's hard to imagine anyone would be silly enough to build a new device that couldn't. Therefore, enable the NETIF_F_HIGHDMA feature for IPoIB. This has no effect for no, but is needed when we enable gather/scatter support and checksum stateless offloads.
