[lwip-users] Possible contribution?

[Colin Nichols]

Hi all,

First off, I just want to say that lwIP is pretty cool!

I have a possible contribution... I ported the BSD driver for the 
Broadcom NetXtreme II cards to my own OS... These are server cards found 
on many Dell blades and elsewhere throughout the server room.

It wouldn't be hard to abstract out the OS-dependent parts (DMA memory 
allocation, watchdog timer creation, PCI access functions, etc); people 
could then use their own OS's functions and incorporate with lwIP/their 
OS however they like.

Some parts of the driver are REALLY rough (especially dealing with the 
MII bus and PHY) but it's functional (at least for the card I've got, 
5709S).  I'm working on cleaning it up and expanding support to the 
other cards in the NetXtreme II line.

Also, pbufs aren't really integrated, making it far from zero-copy when 
used with lwIP.

Nevertheless, I wanted to ask if this would be a useful contribution.  
Doesn't seem like there's much support out there for x86 platforms, 
especially on the server side.  I'd do my best to clean it up before 
uploading it to wherever.


Best regards,
Colin
