Subject: IB: Set GIDs correctly in ib_create_ah_from_wc()
X-Git-Tag: v2.6.16-rc1~678^2
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4f8448dfe8d3804fadad90c9b77494238b4a4eae;p=linux-2.6

IB: Set GIDs correctly in ib_create_ah_from_wc()

ib_create_ah_from_wc() doesn't create the correct return address (AH)
when there is a GRH present (source & dest GIDs need to be swapped).
