Subject: [PATCH] opensm/osm_pkey_mgr: clean partition enforcement on inter-switch links
Date: Tue, 03 May 2011 11:02:07 +0300	[thread overview]
Message-ID: <4DBFB67F.2090400@dev.mellanox.co.il> (raw)

clean partition enforcement on inter-switch links

after connectivity change from switch-host to switch-switch the
partition enforcement bits were not cleared on the port.
since the pkey table is not set on inter-switch links,
packets with pkey other than default are dropped.
