* nearly every file: Use macros defined in ip_addr.h (some of them new)
to work with IP addresses (preparation for bug #27352 - Change ip_addr
from struct to typedef (u32_t) - and better code).
2010-01-31: Simon Goldschmidt
* netif.c: Don't call the link-callback from netif_set_up/down() since
this invalidly retriggers DHCP.
