>Description:
if_re has a bug
If you set ether address in ifconfig, ping fails,
but after, if you change interface to promiscuous mode ping become work.



re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=389b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC>


re0 at pci0:2:0:0: class=0x020000 card=0x816810ec chip=0x816810ec rev=0x06 hdr=0x00
    vendor     = 'Realtek Semiconductor Co., Ltd.'
    device     = 'RTL8111/8168B PCI Express Gigabit Ethernet controller'
    class      = network
    subclass   = ethernet

>How-To-Repeat:
/etc/rc.conf

ifconfig_re0="inet 192.168.0.2/24"	 	ping works

ifconfig_re0="inet 192.168.0.2/24"
ifconfig_re0_alias0="ether 00:02:1a:2b:3c:4d"	ping fails

tcpdump -i re0 				ping works until Ctrl+C :)
