[PATCH 7/8] eth-filter: improve the demuxer function |
Date: |

Handle multiple request types as recommended by the Mach Server
Writer's Guide section 4, subsection "Handling Multiple Request
Types". This avoids initializing the reply message in every X_server
function. The reply message has already been properly initialized in
libports, so there is no need to call mig_reply_setup.
* eth-filter/filter.c (filter_demuxer): Improve the demuxer function.
Also, move it below the ethernet_demuxer function to avoid the need
for a forward declaration. Prioritize the ethernet_demuxer.
