rtnl: fix info leak on RTM_GETLINK request for VF devices
[ Upstream commit 84d73cd3fb142bf1298a8c13fd4ca50fd2432372 ]
Initialize the mac address buffer with 0 as the driver specific function
will probably not fill the whole buffer. In fact, all in-kernel drivers
fill only ETH_ALEN of the MAX_ADDR_LEN bytes, i.e. 6 of the 32 possible
bytes. Therefore we currently leak 26 bytes of stack memory to userland
via the netlink interface.
