Hello,

Here's a patch for a first attempt at static leases for udhcpd.
Included in the tarball are 2 files (static_leases.c, static_leases.h)
and a patch against the latest cvs.

In the config file you can configure static leases with the following
format:

static_lease 00:60:08:11:CE:4E 192.168.0.54
static_lease 00:60:08:11:CE:3E 192.168.0.44

Comments/suggestions/improvements are welcome.


Wade
