Hi, the diffrence b/w alloc_etherdev(dev) and ether_setup() is the memory allocation for the device struct, In alloc_etherdev() u dnt have to allocate memory ,it is taken care by the api, but in ether_setup() u hav e 2 allocate memory for the dev struct b4 u pass it on to the api Hope this helps Rgds Anand > > -----Original Message----- > > From: kernelnewbies-bounce@xxxxxxxxxxxx > > [mailto:kernelnewbies-bounce@xxxxxxxxxxxx]On Behalf Of > > Mandeep Singh Sandhu > > Sent: Thursday, March 04, 2004 2:28 PM > > To: kernelnewbies@xxxxxxxxxxxx > > Subject: ethernet driver : how to allocate space for > net_device struct > > > > > > 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.
