From 9dcc0e58e2913f7e6ffba64c27fe5c2f2c7b845c Mon Sep 17 00:00:00 2001 From: Bryan O'Sullivan Date: Tue, 23 May 2006 11:32:35 -0700 Subject: [PATCH] IB/ipath: enable PE800 receive interrupts on user ports Fixed so it works on the PE-800. It had not previously been updated to match PE-800 receive interrupt differences from HT-400.
