+This patch fixes the network driver cpmac.c for compilation with
+configuration option CONFIG_NETDEVICES_MULTIQUEUE.
+
+These compiler warnings are fixed by the patch:
+drivers/net/cpmac.c: In function 'cpmac_end_xmit':
+drivers/net/cpmac.c:630: warning: passing argument 2 of 'netif_subqueue_stopped' makes pointer from integer without a cast
+drivers/net/cpmac.c:641: warning: passing argument 2 of 'netif_subqueue_stopped' makes pointer from integer without a cast
+drivers/net/cpmac.c: In function 'cpmac_probe':
+drivers/net/cpmac.c:1128: warning: unused variable 'i'
+
+During runtime, the unpatched driver raises a fatal runtime exception.
+This is fixed by calling __netif_subqueue_stopped instead
+of netif_subqueue_stopped, too.
+
+Two additional code parts were modified for CONFIG_NETDEVICES_MULTIQUEUE
+because other drivers do it in the same way.
