This series introduces support for the NC-SI protocol to u-boot,
functionality which so far has only been available in vendor trees.
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).
Since the RFC[0] the changes have been split out into a few different
patches to make the overall changes more obvious. Additionally a few
small improvements have been added including adding a check to see if
NC-SI is already configured, and marking the PHY bus "reset" as invalid
since it does not define a bus.
An example of NC-SI setup before a normal network command:
=> dhcp
net_loop: configuring NCSI first
ethernet at 1e660000: link up, 100 Mbps full-duplex mac:0c:c4:7a:d5:48:43
NCSI: probing channels
NCSI: configuring channel 0
NCSI: configuration done!
BOOTP broadcast 1
BOOTP broadcast 2
DHCP client bound to address 10.61.161.188 (255 ms)

Changes in v2:
- Fix endianess issue when setting MAC address
- Make checksum offsets easier to read
- Instantiate per-phy ncsi_priv structures
- Update ncsi command help text
- Used update ncsi-pkt.h version to include SPDX header
