Hi guys
I am planning to build universal device driver for Ethernet
controller . It can work for any type of hardware
I want to make general framework for the driver and it is
configurable or we make a table depend on futures exist in particular
vender chip in particular version
It may be replace all drivers in the Linux kernel tree and only one
Ethernet driver it is easy to understand and it is easy to add new
future or new chip into this driver and its more efficient
Because we are going to implement driver which works 10Mbps to 10Gbps
so this architecture gives us very efficient and very less effort
because everyone working on different driver instead of one driver
I think you guys understand what I have planned right ? then please
share your experience with me
Is it right thing to do ?
Is it acceptable in Linux tree ?
If you have any plan where to start and how to start?
And other then here may I need ask any help from other place
Like Linux kernel mailing list linux-net,netdev because I am new
to this mailing list I am not worked before as open source contributor
Regards

Huh! I have just replied to this in comp.os.linux.networking

Sorry to state the obvious, but that makes no sense. You will either
have to optimize your drive individually for every chip or not
optimize it. Neither way makes any sense.

No. In fact, it makes no sense at all. The driver would have to be
able to handle every possible quirk and layout of every network
controller, past, present, and future. That would be a horribly awful
beast, not optimized for anything, and impossible to debug.
If you needed to add a workaround for a quirk in a particular
controller, you'd need to figure out if that workaround was suitable
for every other controller ever made. To test a major design change or
improvement, you'd need every controller the driver was used on.
It's an absolutely terribly awful idea in every possible way.

Sure, if you can make it work. But that will never happen.
> If you have any plan where to start and how to start?
I would suggest starting by thinking of an idea that makes some kind
of sense.

Having written a few network drivers for different hardware, I'd like
to explicitly second that: Capabilities (and bugs!) of NIC-hardware
vary wildly and a 'generic ethernet driver' required to handle
hundreds, if not thousands, of special cases in its lower level parts
would be an unwieldy monstrosity I would certainly rather steer clear
off. An IMO somewhat more sensible idea would be to abstract common
parts of existing ethernet drivers into an ethernet driver support
library. But even this would be something I'd consider of very limited
usefulness: Typically, computers don't have many different types of
NICs at the same time and duplicated code which has never been
compiled or just sits on one of nowadays disk drives matters very
little, if at all. But the additional abstraction makes all of the
drivers using it somewhat more complex and more difficult to
understand. |

Dude, you need to have your medication adjusted.
That's about like declaring that you're planning on writing the
"universal program" that will work for all kinds of people
doing all sorts of applications on all OSes.
