You could do, what I ve done:
change the name of the interface, the driver creates:

go to:
cd <path-to-hostap>/driver/modules/
grep -n wlan hostap_hw.c

//this should show you the line-numbers where the interface name is 
created: There are two lines:
xxxx:  sprintf(dev->name, "wlan%d", i++);
yyyy:  memcpy(dev->name, "wlan%d",7);

open the file hostap_hw.c in an editor and replace this two occurrencies 
with the string "eth", recompile the host_ap driver, and your interface 
will now be called ethX.
