From 36026ecc20e5df722bbe2ea9e451c73d686ef107 Mon Sep 17 00:00:00 2001 From: Moni Shoua Date: Mon, 23 Jul 2007 10:07:42 +0300 Subject: IB/core: Ignore membership bit in ib_find_pkey() ib_find_pkey() is used as a replacement for ib_find_cached_pkey(), and the original function ignored the membership bit when searching for a P_Key, so ib_find_pkey() should ignore the bit too. In particular, IPoIB turns on the P_Key membership bit of limited membership P_Keys when creating a child interface and looks for the full membership P_key. This broke if a port was a partial member of a partition when IPoIB switched from ib_find_cached_pkey() to ib_find_pkey(), and this change fixes things again.
