Lu Ding 818d90efda net: gptp: Fix sync_receipt_time calculation in gptp_mi
Fix #42800
Both pss->rate_ratio and port_ds->neighbor_rate_ratio are double type
but sync_receipt_time is uint64_t. If pss->rate_ratio is less than 1
or sync_receipt_time * port_ds->neighbor_rate_ratio is less than 1,
sync_receipt_time becomes 0 due to double to uint64_t cast.
Assign port_ds->neighbor_prop_delay to sync_receipt_time first to fix
this issue.

Robert Lubos c479458392 net: arp: Fix ARP retransmission source address selection
There was a problem with source address selection for ARP
retransmissions, when an ARP entry was already pending. In such case,
the `entry` value passed to `arp_prepare()` is NULL, which in result
caused the `current_ip` variable being used as the source value. The
problem with this approach is, that the `current_ip` is only set in
IPv4 autoconf, the Ethernet L2 does not set this variable. In result,
every retransmission of an ARP packet was sent with unspecified source
address, preventing the response from being handled.

Fix this by partially restoring the behaviour of the ARP source address
assignment from before IPv4 autoconf was introduced. If the ARP is sent
by the IPv4 autoconf, use the `current_ip` value provided. If entry is
not set, use the source IPv4 address set in the actual data packet.
Otherwise, search for a source address on the interface corresponding to
the `entry`.

Jukka Rissanen ce2abc26b5 net: capture: Catch sent and received packets
Create net_l2_send() function which will be called by each L2
sending function so that we can catch all the network packets
that are being sent. Some L2 layers send things a bit differently,
so in those cases call the net_capture_send() directly by the L2
layer.
Add network packet capture call in receive side after the pkt has
been received by the RX queue handler. This avoids calling the
net_capture_send() from ISR context.

Marcin Niestroj c1f7b9f45a net: l2: ethernet: fix k_work API usage in carrier on/off handling
net_eth_carrier_on() and net_eth_carrier_off() call k_work_init() on
work item that can be pending or still be processed in another thread.
This results in undefined behavior.

Initialize work item once and use an atomic flag to switch between
up/down carrier state. Submit work to workqueue whenever up/down carrier
state changes, so that last state is always properly propagated to
network interface layer.

While at it, save network interface pointer during ethernet context
initialization, so that is becomes static (and thread-safe) during whole
ethernet context lifetime.
