net/smc: immediate termination for SMCR link groups
If the SMC module is unloaded or an IB device is thrown away, the immediate link group freeing introduced for SMCD is exploited for SMCR as well. That means SMCR-specifics are added to smc_conn_kill(). Signed-off-by: Ursula Braun <ubraun@linux.ibm.com> Signed-off-by: Karsten Graul <kgraul@linux.ibm.com> Signed-off-by: David S.
