>Description:
no emulation for SIOCGIFHWADDR


>How-To-Repeat:
Use a linux program that calls ioctl() for SIOCGIFHWADDR.  Get EINVAL:

 12868 program CALL  ioctl(0x3,_IO('<89>',0x27,0),0xefbfca90)
 12868 program RET   ioctl -1 errno -22 Invalid argument

>Fix:
The call takes a struct ifreq with ifr_name set to the interface name.
The emulation should probably convert from "eth0" to the first ethernet
interface, from "eth1" to the second, etc.
