BunnyFl measured both calls in firmware 13.42 libSceNet.sprx, run in an
emulator on the module itself. sceNetInitParam returns 0x80410116 for a
null parameter. The first non-null call copies the first 32 bytes of the
parameter and returns 0, and every later call returns 0x80410110, with a
null parameter and after sceNetTerm too, because the flag is never
cleared. sceNetConfigGetIfFlags returns 0x8041130E for a null flags
pointer before anything else. Both replace throws that stood in for the
unknown answers.
The first successful sceNetInitParam still marks the library initialized,
as sceNetInit does here, because the other calls check it. The module
reads only bit 0 of the stored copy's first word, to raise the pool limit
of sceNetPoolCreate from 32 to 128; that limit is recorded as not
modelled, as sceNetPoolCreate here has none.
On macOS, FIONREAD on a datagram socket counts more than the queued
payload, so after one 5-byte datagram sceNetIoctl reported 37.
libkernel's sockets already ask a macOS datagram socket for SO_NREAD,
the size of the next datagram, instead; do the same for sceNetSocket
sockets that are not streams.

sceNetConfigGetIfFlags answers interface 0, lo0 in the sceNetGetIfName
numbering, with IFF_UP | IFF_LOOPBACK | IFF_RUNNING | IFF_MULTICAST, the
flags FreeBSD 11 gives a configured loopback. Other interfaces and a null
flags pointer throw: the library models no other interface.
sceNetInitParam initializes the library as sceNetInit does and returns
its result. NetInitializeParameter's layout is unknown, so its fields are
not read; a null parameter throws because its console result is unknown.
After sceNetInit, the console's sceNetUsleep prints
"[LIBNET] usleep <count>" to standard output for a negative count
before failing with EINVAL, as a payload measured on firmware 13.60
(#9076). AnyPS5 failed without printing it.

On macOS, shutdown(SHUT_RD) on a UDP socket that was never bound does not
wake a thread blocked in recv on it, so sceNetShutdown left the receiver
hanging. Use the receive wait that Windows already has: block on the
socket table until the socket gets a local port or is shut, then poll.
On macOS an unbound socket reports port 0 from getsockname, so the check
looks at the port instead of the Winsock error.
Ported from #8658.

sceNetConnect dissolves a datagram association with the same host call sequence as connect (disconnect_datagram in Export.cpp). The sceNetConnect-to-AF_UNSPEC debt entry only described Linux. On Windows a socket bound to an explicit address keeps it in the same way, and a sendto on the host socket to a non-loopback address fails with Winsock error 10051, where FreeBSD's udp_disconnect() resets the local address.
