[yocto] e100 driver does not build

[Saxena, Rahul]

Yes, the problem was due to missing dependent options..
I had incorrectly assumed that dependent options would get pulled in 
or perhaps a error would  be generated.
It worked after I added following 3 options stated as dependent options
in a Kernel configuration database that I saw:

CONFIG_ISA
CONFIG_EISA
CONFIG_NET_PCI

I am still iterating to check if all three of the above are really needed or
or if just the CONFIG_NET_PCI option is needed. 

I had enabled the option using a .cfg file.  Also checking again to see if a warning
gets generated when the dependent options are not included.

BTW what does a message such as following in the .config file mean ?

"CONFIG_xxxxx is not set"  


Thanks
Rahul

This is most likely what it is.

Out of curiosity, how did you enable the option ? Via a config fragement
(.cfg file) or via menuconfig .. or something else?

If you tried to set something via a fragment and it doesn't make it to
the final .config, you should see a warning during the kernel build
phase.
