From: Sathya Perla <sathya.perla@...lex.com>
To: <netdev@...r.kernel.org>
Subject: [PATCH net-next 2/4] be2net: refactor VF setup/teardown code into be_vf_setup/clear()
Currently the code for VF setup/teardown done by a PF (if_create, mac_add_config, link_status_query etc) is scattered; this patch refactors this code into be_vf_setup() and be_vf_clear().
The if_create/if_destroy/mac_addr_query cmds are now called after the MCCQ is created; so these cmds are now modified to use the MCCQ instead of MBOX.
