Before you start you need to consider the licensing issue. Linux is
GPL. eCos is modGPL. The modification means that the viral effects of
the GPL do not spread to the application code. However if you port the
GPL wireless driver into eCos, the GPL from the driver will spread
over all of eCos and to the application. ie you need to make your
application sources available. You need to decide if this is
acceptable to you. 

We won't be able to accept your code into the eCos repository
obviously because it is GPL.

Also, you might consider talking a look at the FreeBSD wlan
drivers. They will probably have both a more suitable licence and will
be easier to port since the TCP/IP stack in eCos is from FreeBSD.
