Titles import sceNetCtlGetInfoV6, and a missing import stops them at
load. The checks that need no answer layout are implemented; every code
throws when the host has IPv6, since the layout of the answer is not
verified.
libSceNetCtl exports sceNetCtlGetStateV6, sceNetCtlRegisterCallbackV6
and sceNetCtlUnregisterCallbackV6 but not sceNetCtlGetInfoV6 (NID
Jy1EO5GdlcM). Dragon Ball Xenoverse 2 (PPSA08587) imports it, and an
import that no system library exports stops a title before its entry
point: on Linux ld.so refuses the relinked executable with "undefined
symbol: Jy1EO5GdlcM", and on Windows the entry stub prints "FAIL:
unresolved ELF import Jy1EO5GdlcM from libSceNetCtl.prx" and raises
0xC0000139. The title's tester reports that it does not call the
function before its loading screen.
It is a Sony network-control call with no FreeBSD counterpart, and
neither its parameters nor the IPv6 info layout are known, so it is
declared without parameters and throws through
NotImplemented_nid_no_patch, as CONTRIBUTING.md asks of exports that
cannot be implemented. The gap is recorded in
docs/dev/debt/libSceNetCtl.md.

sceNetCtlRegisterCallback and sceNetCtlRegisterCallbackV6 stored only
the function and dropped its argument, and sceNetCtlCheckCallback
returned 0 without calling anything, so a title that polls
sceNetCtlCheckCallback until its callback reports IPOBTAINED never
got the event.
Each callback slot now keeps the function, its argument and the last
event it received; unregistration clears the slot. With no IPv4
callback registered, sceNetCtlCheckCallback returns 0 without querying
the host. Otherwise it takes the state from the same host-interface
predicate as sceNetCtlGetState, IPOBTAINED (3) or DISCONNECTED (1)
(shadPS4 src/core/libraries/network/net_ctl_codes.h L27-29
@15abf68c9b52), marks the IPv4 slots whose last event differs and
calls them on the calling thread with their argument after the lock is
released, so a callback can unregister itself. Delivery once per state
change and slot follows KytyPS5 src/libs/network.cpp @9e41d8320a27
(NetCtlCallbackSlot L3447-3451, NetCtlCheckCallback L3648-3661,
NetCtlRegisterCallback L3687-3707); shadPS4 net_ctl_obj.cpp L47-57
delivers on every check instead, and the debt entry records the
difference and that KytyPS5 calls the callbacks under its lock.
sceNetCtlTerm clears both tables, as KytyPS5 NetCtlTerm (L3625-3633)
does. V6 slots keep their argument but get no event, since no source
says which call delivers them.
NetCtlCallback is now an APS5_VABI pointer, so the Windows build calls
the guest function with the System V ABI.

Since #5056, sceNetCtlGetInfo throws for every info code it does not
model. Ghost of Yotei (PPSA26344) asks for code 12, the DHCP host name,
during boot and now aborts one second in.
The configuration #5056 reports (wired, DHCP, HTTP proxy off) sets no
DHCP host name, no PPPoE user name and no proxy server, so codes 12, 13
and 20 now return 0 with an empty string. The Wi-Fi codes (5-10) and
the proxy port (21) still throw. GuestNetCtl checks the three empty
answers and keeps the throw check for the rest; the libSceNetCtl debt
line says the same.
sceNetCtlGetState reports IPOBTAINED from the host's addresses, but
sceNetCtlGetInfo returned NOT_CONNECTED for every code. It now answers
from the host interface that holds an IPv4 address, preferring the one
with the default route: its address, netmask, gateway, MTU and DNS
servers. The link is presented as wired, connected, configured by DHCP
and without a proxy, with the Ethernet address sceNetGetMacAddress
reports. A null info returns INVALID_ADDR and a code outside 1..21
INVALID_CODE; the Wi-Fi, DHCP host name, PPPoE and proxy server codes
throw.
