NAME
       dev_getbyhwaddr_rcu - find a device by its hardware address

SYNOPSIS
       struct net_device * dev_getbyhwaddr_rcu(struct net * net, unsigned short type, const char * ha);

ARGUMENTS
       net
	   the applicable net namespace

       type
	   media type of device

       ha
	   hardware address

DESCRIPTION
       Search for an interface by MAC address. Returns NULL if the device is not found or a pointer to the device. The caller must hold RCU or
       RTNL. The returned device has not had its ref count increased and the caller must therefore be careful about locking
