ethernet driver : how to allocate space for net_device struct

["Mandeep Singh Sandhu" <mandeep_sandhu@xxxxxxxxxxx>]

hi all,
in my ethernet driveres intialization function, how shud
i allocate space for the net_device structure???

i have seen in 8139too.c a call to "alloc_etherdev(dev)".
is this the preffered way to allocate space for the net_device
struct. In rubini's book he has mentioned the use of
"ether_setup" (there is no mention of "alloc_etherdev")
to partially fill up the net_device struct, but this fxn
is not used in some real world drivers like the driver for
realtek card (8139too.c). where can i get info on what
functions like "alloc_etherdev" do???

TIA
