Jukka Rissanen ac56fd8d27 tests: net: Increase stack sizes for coverage testing
We need to increase the stack sizes if user enables CONFIG_COVERAGE
option. You can test this by this command

    sanitycheck --coverage -p qemu_x86 -T tests/net/udp \
                -T tests/net/mgmt  -T tests/net/mld

This is partial fix for issues described in #17323

Tomasz Bursztyka b2b21412ae net/connection: Removing cache feature
There were various flaws in it that motivated its removal:

- No hash collision handling mechanism. In case that would happen, the
behavior of the network connection would be unknown. This is the main
drawback
- The lookup is not that much more efficient than the default one. The
only difference of gain is in connection comparison (a u32t comparison
vs a full connection compare). But the list handling is the same. It's
made worse by the presence of a negatives match array which can be
easily filled in and becomes then fully usless, appart from consuming
CPU. As well as adding a new connection: it requires the whole cache
to be cleared which is unefficient.
- Not memory efficient, even compared to a proper hash table.
Two arrays instead of one etc...

All of this could be fixed by using a proper hash table, though it
remains to be seen if such object could fit in Zephyr core.

Jukka Rissanen cf6a870863 tests: net: udp: Increase network buffer counts
In some hw like Atmel SAM-E70, the original amount of network
buffers is too small so increasing it slightly.
Also generate proper error if this happens in the test so it
is easier to figure out.

Fixes #8865

Leandro Pereira da9b0ddf5b drivers: Rename `random` to `entropy`
This should clear up some of the confusion with random number
generators and drivers that obtain entropy from the hardware.  Also,
many hardware number generators have limited bandwidth, so it's natural
for their output to be only used for seeding a random number generator.

Anas Nashif ca0ad13a61 net: enable SLIP only on QEMU targets
In many networking tests we had to configure SLIP in the prj.conf
leaving those configurations Qemu specific. This change enables SLIP for
QEMU targets automatically and allows reuse of prj.conf for multiple
boards.

Additionally, the TUN options is removed. This option was not used
anywhere.

To enable self-contained networking tests that do not depend on SLIP, we
introduce the new option NET_TEST which disables TAP and allows testing
in QEMU without the need for a host interface.

Jukka Rissanen 3604c391e6 net: udp: Remove NET_UDP_HDR() macro and direct access to net_buf
Remove NET_UDP_HDR() macro as we cannot safely access UDP header
via it if the network packet header spans over multiple net_buf
fragments.

Fixed also the UDP unit tests so that they pass correctly.

Jukka Rissanen 69b25c0788 net: conn: Check UDP and TCP checksum before accepting packet
We did not check UDP or TCP checksum to be valid after receiving
the packet. Fix this so that the checksum is validated when
packet is received in connection handler. As the checksum validation
can be resource intensive, do it after we have verified that
there is a connection handler for this connection.

The checksum calculation can be turned OFF if needed, but it is
ON by default.

Tomasz Bursztyka bf964cdd4c net: Renaming net nbuf API to net pkt API
There have been long lasting confusion between net_buf and net_nbuf.
While the first is actually a buffer, the second one is not. It's a
network buffer descriptor. More precisely it provides meta data about a
network packet, and holds the chain of buffer fragments made of net_buf.

Thus renaming net_nbuf to net_pkt and all names around it as well
(function, Kconfig option, ..).

Though net_pkt if the new name, it still inherit its logic from net_buf.
'
This patch is the first of a serie that will separate completely net_pkt
from net_buf.

Jukka Rissanen d32503f57e net: nbuf: Split one global DATA pool to RX and TX DATA pools
If we receive lot of packets, it might happen that we exhaust
all the DATA buffers in the system. This would prevent from
us sending anything to the network.
Change this by splitting the DATA buffer pool into RX and TX
parts. This way RX flooding cannot consume all DATA buffers
that needs to be sent.

Marcus Shawcroft 954baea90b random: Restructure RANDOM Kconfig
Restructure the RANDOM Kconfig to match the structure used in other
drivers with a single top level menu.  Move the true random number
generators to appear first in the menu, with pseudo generators at the
bottom.  Do not present pseudo generators if a true random generator
is presented.

This change implies that tests, samples and applications that require
the random driver interface must now select CONFIG_RANDOM_GENERATOR.

In order for tests and samples to build (and run) on platforms that
have no random driver it remains necessary to select
the CONFIG_TEST_RANDOM_GENERATOR.

Note that CONFIG_TEST_RANDOM_GENERATOR retains its original purpose of
enabling a random driver that delivers non random numbers for the
purpose of testing only.
