From 917690cd035b422b1ac933ac160d26016aa454ac Mon Sep 17 00:00:00 2001 From: Brice Goglin Date: Tue, 27 Mar 2007 21:54:53 +0200 Subject: myri10ge: correctly detect when TSO should be used Correctly detect when TSO should be used on transmit by looking at the skb->gso_size rather than seeing if the frame was larger than our MTU. The old method causes problems when a host with a large (jumbo) MTU is sending to a host with a small (standard) MTU.
