Subject: [PATCH net-next 05/10] net/smc: move link llc initialization to llc layer

From: Karsten Graul <kgraul@...ux.ibm.com>

Move the llc layer specific initialization and cleanup out of smc_core.c
into smc_llc.c (smc_llc_link_init and smc_llc_link_clear). Move all
initialization of a link into the new init function.
