Hello,
Can we write Ethernet driver without using dma ?
But still using sk_buff APIs like done in most drivers ?
Thanks,
Ran

Sure, we have USB network drivers that don't use DMA.

Yup.
What type of hardware are you wanting to write an Ethernet driver for?
thanks,

OMAP4, (omap4460), which connect to mac controller implemented in FPGA.
There is no template for ethernet driver, but I see that netx-eth has
quite simple implementation, which looks as a good starting template:
