From af30bd03def39b9b9d26780c37ba32d51cad2772 Mon Sep 17 00:00:00 2001 From: Brice Goglin Date: Thu, 24 Jul 2008 17:53:28 +0200 Subject: myri10ge: do not forget to setup the single slice pointers part of commit 0dcffac1a329be69bab0ac604bf7283737108e68 upstream (the upstream multislice patch contains the same fix within myri10ge_alloc_slices() which does this for every slice) Even if we don't have multiple slices in myri10ge in 2.6.26, we already use some multislice-aware routines that need the slice state pointers to mgp and dev to be valid. This patch fixes a regression where configuring the interface up would oops in myri10ge_allocate_rings() when using ss->mgp (and later when using ss->dev).
