This changes pfilter-builder.c so it really build in user space, but removing register setting and creating output files instead. Running this program creates 3 files, that correspond to the previous three #ifdef conditions. The files are: rules-plain.bin this is used for the no-etherbone configuration rules-ebone.bin etherbone setup rules-e+nic.bin etherbon plus 7solution's wr-nic packet filter The files begin with a magix 0x11223344 word, that allows the soft-core to fix any endianness difference (so no hairy mishaps are expected when switching to a different soft-core). Then the 40-bit command words are saved as 64-bit vaules, LSB-first. The output file is thus an odd number of words and no 64-bit alignment is required. The first three instructions of the packet filter are used to compare the destination mac address of the frame. We now use a fake mac address, and the LM32 code will change it while programming the binary. Please look at this commit while ignoring white-space, as it changes indentation while turning #ifdef/#else into if()/else . Signed-off-by: Alessandro Rubini <rubini@gnudd.com>
