Message-ID: <1424683216-29611-8-git-send-email-sathya.perla@emulex.com>

Subject: [net-next PATCH 7/9] be2net: refactor adapter resource initialzation sequence into be_resume()
From: Kalesh AP <kalesh.purayil@...lex.com>
Most of the adapter initialisation sequences performed in be_resume(),
be_eeh_resume() and be_err_recover() are same. Renamed be_resume() to
be_pci_resume() and moved the common code to a new routine be_resume() to
avoid code duplication.
