Subject: [PATCH ibacm 2/8] acm.c: In acm_port_up, handle noncontiguous pkeys
Date: Tue, 06 Aug 2013 07:45:17 -0400	[thread overview]
Message-ID: <5200E1CD.6070705@dev.mellanox.co.il> (raw)


There can be "holes" in pkey table although this is not usually the case
but since IBA spec allows for this, it should be handled.
