Hi Chris,

Thank you for the note.  I was able to get the LEDE build environment
working and recompiled dnsmasq with the patch.  The patch, when applied to
v2.77, worked and DHCP relay is working as expected in my use case.  

Thanks for the help!

Ray

DHCP relay was broken by a commit shortly before 2.76 was released [1], and
this breakage was itself recently fixed by a commit that'll eventually make
it into 2.78 [2]. If you're able to compile dnsmasq yourself, could you
check that [2] fixes the problem you're seeing?
