From bcacb897569f0e7aab7643b22567d8de22ef9dfc Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Mon, 10 Oct 2011 10:53:41 +0200 Subject: IB/mlx4: Enable 4K mtu for IBoE The IBoE port MTU is derived from the corresponding Ethernet netdevice MTU, which can support jumbo frames of 9K, and hence surely supports the max IB mtu of 4K.
