Ok, there are some reasons to delay the DHCP client integration until I
have
got the ARP and timer stuff solved.

While implementing the ARP check (to check if the offered IP address is not
in use on the network) I came across some difficulties.

At least one problem was a bug in ARP.c (I'm using the 0.5.0 tree with some
bugfixes from the list):

// bug PROTOLEN must be HWLEN
//#define ARPH_PROTOLEN_SET(hdr, len) (hdr)->_hwlen_protolen = HTONS((len)
| (ARPH_PROTOLEN(hdr) << 8))
#define ARPH_PROTOLEN_SET(hdr, len) (hdr)->_hwlen_protolen = HTONS((len) |
(ARPH_HWLEN(hdr) << 8))

Other than this, the ARP packet crashes my packet analyzer Ethereal
(.soureforge.net) for a reason
I'll not be able to find out in the next half hour :)

After that, I'm off for a week, so first work on the DHCP client (on my
behalf) will be in a day or ten.

Regards,

Leon.
