Subject: [PATCH 12/16] libfcoe, fcoe: consolidate the fcoe_ctlr_get_lesb/fcoe_get_lesb
Date: Wed, 12 Dec 2012 15:23:08 -0800	[thread overview]
Message-ID: <20121212232308.13084.2948.stgit@fritz> (raw)
In-Reply-To: <20121212232203.13084.3630.stgit@fritz>

From: Yi Zou <yi.zou@intel.com>

Similarly they can be moved into libfcoe instead of being private to fcoe now.
Also add comments particularly on the term LESB to the corresponding function.
