net.dhcp = false applies ip/mask/gw/dns on link up (DHCP client stopped).
PTP/TX/SAP sockets are bound to the address, so a changed IP setup reboots
the device; with DHCP on, the static fields (UI fills them with the lease)
don't count as a change. Validation: contiguous netmask, not the network or
broadcast address, gateway in the subnet. The page follows the device to the
new address after saving. Checked: DHCP -> static .245 (PTP, TX, SAP, SDP
origin, mDNS on the new address) -> DHCP.
