net/smc: convert static link ID to dynamic references
As a preparation for the support of multiple links remove the usage of a static link id (SMC_SINGLE_LINK) and allow dynamic link ids. Signed-off-by: Karsten Graul <kgraul@linux.ibm.com> Reviewed-by: Ursula Braun <ubraun@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
