Hi @michael-dev,

Is it necessary to apply the patch in the kernel 3.16.0-37-generic? Because I have checked in the kernel source[1] and they looks like the same behavior added by your patch.

Hi @michael-dev,

I would like to know if you know about the 'option 82'. And what do you think to add support to update/insert the informations in the dhcp request. I made something like that using the 'relay concept'[1], but the idea is to do like cisco/3com and another appliance in 'snooping' mode.

.

The binary should report some info about the source code.

See http://www.atmel.com/webdoc/avrlibcreferencemanual/FAQ_1faq_binarydata.html
for an approach.
