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 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.
