Re: example device driver with manufacturer's specification

["tejas khatiwala" <socretez@xxxxxxxxx>]

thanks Greg.. that is really really cool.. so if i'm not mistaking
RTL8139C+.pdf.bz2 is specification associated with driver
source/drivers/net/8139cp.c.. if it is then it is really cool as I've
been taking that source as my base reference to learn many things.
please correct me if i'm wrong..
         i've one more question.. I've this Linksys PCI Wireless
ethernet adapater (WMP11.. i don't know the revision).. as far as i
know.. it is only known to work with ndiswrapper till this date.. so i
was thinking to write driver or at least experiment  with it..
         so the thing i wanted to know was device id.. i looked it
up with "lspci -vv" and it was there.. i looked up the bus it was
connected with under /sys/bus/pci/<bus#>/deivces and it showed me
vendor id to be 0x14e4 and device id to be 0x4301.. also.. "lspci -vv"
identified vendor as Broadcomm Corp. and enlisted "Linksys" as
subsystem.. now 0x14e4 indeed is Broadcomm's vendor id whereas Linksys'
vendor id is 0x1737.. so my question is: given this info.. can i trust
0x4301 to be correct device id ??
         I will really appreciate your help.

There are several others in the specs directory.  I think everything
there is open.

Thanks a ton, Greg. I was never able to find a consolidated site for many specs like this till now.

FYI: Not everything in the specs folder is a nic spec, but many of them are.
