The activenics{"!remote!"} hash key is checked at line 1940 but never
set by any code path — neither the dhcpinterfaces parsing nor the
querynics discovery populates it. This causes the guard to always
evaluate true, hitting next and silently skipping every !remote!
network when dhcpinterfaces is defined in the site table or on a
service node.
Remove the dead check so remote networks are processed correctly.
The inner activenics{$netif} check (which uses the actual interface
name after stripping the !remote! prefix) is the correct guard and
is preserved.

Add a shared OMAPI policy helper for ISC DHCP and DDNS so administrators can select the key name, signing algorithm, and omshell path from the site table while preserving the existing xcat_key hmac-md5 default.
Keep local ISC updates from hanging indefinitely when omshell does not exit, and use a static host-declaration fallback for local Ubuntu ISC releases where omshell is unstable for xCAT host updates.

Previously, makedhcp warned but still created host entries without
a static IP reservation when a node's address fell inside the
dynamic range. The node would silently get a random IP from the
pool instead of its configured address.
Now errors and skips the node on all four DHCP paths (ISC v4/v6,
Kea v4/v6) with a clear message telling the admin to move the IP
outside the range or adjust the dynamic range.
This makes ISC DHCP and Kea behavior consistent and aligns with
xCAT's design: the dynamic range is for hardware discovery,
known nodes should have static IPs outside it.
Closes#6539
Machines that use Infiniband for PXE booting need to have the
dhcp-client-identifier set in the lease block.
Without it, they will not get the lease from the server.
- if all service nodes not running dhcp, to treat it as disjointdhcps=0
- nodeset will send request to MN by default even if disjointdhcps=1
- Move out of the dhcp service checking from opts pre-check, and do it just before real makedhcp handling.
- for non-disjoin mode, forward the request to MN also if preprocess is handled on SN
- for disjoint mode, forward the request to dhcpservers which is serving dynamic range
Add a MTU column to the networks table. If set, this will configure the MTU in
DHCP so that nodes will have the correct MTU during provisioning. This is
important for large systems to enable jumbo frames to reduce CPU usage when
copying diskless images over the network (before the confignics postscript can
run to set the desired MTU).
