The ring_buf implementation is basically used as an array of net_buf
pointers in the RX path. The tail and head indexes are taken from the
RX descriptors and not from the ring_buf. That's why for example the
fact that head is never initialized doesn't cause problem. Only len is
used in free_rx_bufs(), but anyway this function is plainly broken as
it always free the first net_buf and doesn't set it back to NULL.

Scale down the TX path of the GMAC driver by waiting for a packet to be
fully sent before returning from the send function. This has a small
performance impact, but has a few advantages:
- It allows the Ethernet code to modify the packet afterward, fixing PTP
support on this board (see PR #12563).
- It returns an error to the IP stack in case of a transmit failure.
- It doesn't require net_buf to be thread safe.
This change can be reverted by changing GMAC_MULTIPLE_TX_PACKETS from 0
to 1.

In the SimpleLink wifi driver, the socket family value needs to be
converted to the SL_* equivalent to be understood by the SimpleLink
API, instead of being passed straight in.
While not strictly necessary, we are doing the same for socket type
and protocol values to future-proof ourselves in case similar changes
happen to the values defined for these in Zephyr header files.

The GMAC driver tries to ensure that it can always send a complete
Ethernet frame. However in the TX path this is the problem of the IP
stack: if the buffers can't be allocated, they won't be sent. Therefore
just drop the check.

Now that the RX packets are limited to the RX workqueue only, we can
reduce ETH_SAM_GMAC_BUF_RX_COUNT to 12 and still be able to receive a
full Ethernet frame. This reduces the minimum NET_BUF_RX_COUNT required
by this driver to 24.

The SAM GMAC Ethernet driver currently keeps a reference to the packet
being sent in addition than keeping of references of the fragments. In
practice this is only needed when PTP is enabled, otherwise the driver
only need to prevent the fragment (or even their content) to be changed.
Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
The SAM GMAC Ethernet driver uses scatter gather DMA to transmit data.
Each fragment of a network packet is mapped from a set of descriptors
that is used by the controller to do the DMA transfer. This means that
the packet is not necessary sent when the send() function returns. For
that reason the driver calls net_pkt_ref() on the packet to prevent it
from being freed. It is then unreferenced with net_pkt_unref() in the
TX ISR when the packet has effectively been sent.
However this doesn't work if the packet is modified in the meantime,
like it will be done in PR #12563 to remove the Ethernet header
contained in the first fragment. To avoid that, call net_pkt_frag_ref()
on each fragment of the packet, and unreferenced them with
net_pkt_frag_unref() in the TX ISR when the packet has effectively been
sent.
