Patch from Eric Norum <eric@skatter.usask.ca>:

Browse Source 
1) Socket timeout field changed from `short' to `long'.  This makes longer
       timeouts possible.  With a 1 kHz system clock the old system allowed
       timeouts only up to a little over 30 seconds!  This change is a
       slightly cleaned-up version of the patch proposed by Ian Lance Taylor.

    2) Major changes to BOOTP/DHCP reply handling.  Now supports much of
       RFC2132.  These changes were done at the request of, and with the
       assistance of, Erik Ivanenko.

    If you're making changes, you might want to change the network
    supplement  Essentially just do a global search and replace of BOOTP
    with BOOTP/DHCP.
