DSA stands for Distributed Switch Architecture and it covers switches that
are connected to the CPU through an Ethernet link and generally use frame
tags to pass information about the source/destination ports to/from CPU.
Front panel ports are presented as regular ethernet devices in U-Boot and
they are expected to support the typical networking commands.
DSA switches may be cascaded, DSA class code does not currently support
this.Signed-off-by: Alex Marginean

This introduces support for the NC-SI protocol, modelled as a phy driver
for other ethernet drivers to consume.NC-SI (Network Controller Sideband Interface) is a protocol to manage a
sideband connection to a proper network interface, for example a BMC
(Baseboard Management Controller) sharing the NIC of the host system.
Probing and configuration occurs by communicating with the "remote" NIC
via NC-SI control frames (Ethernet header 0x88f8).This implementation is roughly based on the upstream Linux
implementation[0], with a reduced feature set and an emphasis on getting
a link up as fast as possible rather than probing the full possible
topology of the bus.
The current phy model relies on the network being "up", sending NC-SI
command frames via net_send_packet() and receiving them from the
net_loop() loop (added in a following patch).The ncsi-pkt.h header[1] is copied from the Linux kernel for consistent
field definitions.[0]: https://github.com/torvalds/linux/tree/master/net/ncsi

Part of the env cleanup moved this out of the environment code and into

The net_random_ethaddr() tries to get some entropy from different
startup times of a board. The seed is initialized with get_timer() which
has only a granularity of milliseconds. We can do better if we use
get_ticks() which returns the raw timer ticks. Using this we have a
higher chance of getting different values at startup.Signed-off-by: Michael Walle

The inline functions net_read_u32() and net_copy_u32() have been created to
copy unaligned u32. But this is not obvious to the compiler. GCC 9.1
introduces a check -Werror=address-of-packed-member which leads to a build
error on Travis CI:net/bootp.c: In function ‘dhcp_send_request_packet’:

Acked-by: Joe Hershberger -
Peter originally sent a fix, but it breaks a number of other things.
This addresses the original reported issue in a different way.That report was:
> U-Boot has 1 common buffer to send Ethernet frames, pointed to by
> net_tx_packet. When sending to an IP address without knowing the MAC
> address, U-Boot makes an ARP request (using the arp_tx_packet buffer)
> to find out the MAC address of the IP addressr. When a matching ARP
> reply is received, U-Boot continues sending the frame stored in the
> net_tx_packet buffer.
>
> However, in the mean time, if U-Boot needs to send out any network
> packets (e.g. replying ping packets or ARP requests for its own IP
> address etc.), it will use the net_tx_packet buffer to prepare the
> new packet. Thus this buffer is no longer the original packet meant
> to be transmitted after the ARP reply. The original packet will be
> lost.This instead uses the ARP tx buffer to send async replies in the case
where we are actively waiting for an ARP reply.Signed-off-by: Joe Hershberger

We can call commands like dhcp and bootp without arguments or with
explicit command line arguments that really should tell the code where
to look for files instead.Unfortunately, the current code simply overwrites command line arguments
in the dhcp case with dhcp values.This patch allows the code to preserve the command line values if they
were set on the command line. That way the semantics are slightly more
intuitive.The reason this patch does that by introducing a new variable is that we
can not rely on net_boot_file_name[0] being unset, as today it's
completely legal to call "dhcp" and afterwards run "tftp" and expect the
latter to repeat the same query as before. I would prefer not to break
that behavior in case anyone relies on it.Signed-off-by: Alexander Graf

Add a new command 'wol': Wait for an incoming Wake-on-LAN packet or
time out if no WoL packed is received.
If the WoL packet contains a password, it is saved in the environment
variable 'wolpassword' using the etherwake format (dot or colon
separated decimals).Intended use case: a networked device should boot an alternate image.
It's attached to a network on a client site, modifying the DHCP server
configuration or setup of a tftp server is not allowed.
After power on the device waits a few seconds for a WoL packet. If a
packet is received, the device boots the alternate image. Otherwise
it boots the default image.This method is a simple way to interact with a system via network even
if only the MAC address is known. Tools to send WoL packets are
available on all common platforms.Some Ethernet drivers seem to pad the incoming packet. The additional
padding bytes might be recognized as Wake-on-LAN password bytes.By default enabled in pengwyn_defconfig.
