    Subject[patch 35/62] myri10ge: do not forget to setup the single slice pointers
    2.6.26 -stable review patch.  If anyone has any objections, please let
    us know.

    From: Brice Goglin <>

    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).

    Oops reported and patch tested by Lukas Hejtmanek at
