Maximum supported number of interfaces is 32.  More than that should
even work, but you could run into issues (and would probably have
issues getting that many NICs into a box anyway, unless you used USB
NICs as well and that'd just be a mess).  Some things, like the DHCP
server I know for sure off the top of my head, will not work if you
have more than 32.
