I have NOT done it yet. 1) Find an 802.11 chipset that accepts 802.3 packets and handles the 802.11 specific stuff for you. 2) Port one of the ecos ethernet drivers to this chip The original prism chipsets did this (if my interpretation of the documents is right). On page 4-29 of the 'prism driver programmers manual' RM025 (use google) it says ... "In this way, the Host Software can easily be adapted to the requirements of higher software layers. When these layers are “802.11 aware”, the Host Software uses the 802.11 format part of the Header Info. Otherwise, when those layers assume the 802.3 frame format, the PRISM MAC handles the differences between the 802.3 and the 802.11 formats without further involvement of the Host Software." -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
