Why I did it
It was observed that a flood of DHCP packets without rate-limiting can cause BGP flaps or lacp keepalive losses.
This change attempts to prevent or reduce such BGP flaps by enabling appropriate rate-limiting in SONiC for all traffic types.
Work item tracking
Microsoft ADO 17964421:
How I did it
Set a reasonable CIR/CBS value of 300 for queue4_group3 (dhcp, lldp, macsec) and 6000 for queue4_group1.
The value 300 was arrived at after testing with dhcp flooding using ptf (using multiple threads). Throttling at this rate was necessary to ensure that dhcp flooding does not cause BGP flaps.
How to verify it
Verified with this script running from ptf, that BGP flaps don't happen when CBS/CIR is set at 300 for queue4_group3.
import threading
from scapy.all import *
def send_dhcp_discover(intf):
dhcp_discover = Ether(dst='ff:ff:ff:ff:ff:ff',src=RandMAC()) \
/IP(src='1.1.1.1',dst='255.255.255.255') \
/UDP(sport=68,dport=67) \
/DHCP(options=[('message-type','discover'),('end')])
sendp(dhcp_discover,count=100000,iface=intf)
if __name__ == "__main__":
t1 = threading.Thread(target=send_dhcp_discover, args=("eth1",))
t2 = threading.Thread(target=send_dhcp_discover, args=("eth2",))
t1.start()
t2.start()
t1.join()
t2.join()
Verified on Arista-7260CX3-D108C8 running 202012 that the copp rule for queue4_group1 and queue4_group3 do NOT affect BGP packets. To verify this using PTF, the copp rules were modified to set the "CBS" and "CIR" for queue4_group1 and queue4_group3 at 600pps and 50k packets each of "BGP open" and "DHCP Discover" were simultaneously sent from the same PTF port to the DUT. It was verified using "show c cpu" that packets are hitting the cpu queue at 1200 pps (double the configured CIR/CBS for these packet types). This helped conclude that throttling rate is per trap (or packet type) and not per queue.
Verified with updated sonic-mgmt tests ([tests/copp]: Update copp mgmt tests to support new rate-limits sonic-mgmt#8199) on broadcom and mellanox platforms that these traffic types are rate-limited.

#### Description for the changelog
Why I did it
In an effort to allow people to build a slim version of SONiC to fit on devices to small storage, there is a need to disable some unneeded features.
The docker-gbsyncd are only applicable to devices with external gearboxes and might not apply to devices that need a small image.
It is therefore desirable to have a knob to not include these gbsyncd containers.
Work item tracking
Microsoft ADO (number only):
How I did it
Add a new config INCLUDE_GBSYNCD which is enabled by default to retain the previous behavior.
Setting it to n will not include the platform/components/docker-gbsyncd-*.mk.
How to verify it
Set INCLUDE_GBSYNCD = n and witness that docker-gbsyncd images are not present in the final image.
With Debian Bookworm, Paramiko 2.9 or newer will need to be used to be
able to connect to devices running that version of Debian
(specifically, to those running OpenSSH 9.2).
Paramiko is currently on 3.3.1. For now, upgrade to 2.9.5.

* Reduce SONiC image filesystem size
Add a build option to reduce the image size.
The image reduction process is affecting the builds in 2 ways:
- change some packages that are installed in the rootfs
- apply a rootfs reduction script
The script itself will perform a few steps:
- remove file duplication by leveraging hardlinks
- under /usr/share/sonic since the symlinks under the device folder are lost during the build.
- under /var/lib/docker since the files there will only be mounted ro
- remove some extra files (man, docs, licenses, ...)
- some image specific space reduction (only for aboot images currently)
The script can later be improved but for now it's reducing the rootfs
size by ~30%.

How to verify it

Why I did it
Networking devices need to be responsive. Such responsiveness is harmed when the CPU change state.
There is a latency penalty when a CPU is idle (e.g C2) and need to exit this state to come back to C1 state.
To prevent this from happening the CPU should be forced to remain in C1 state.
How I did it
Generalize the cstate forcing to C1 to all Arista products.
This is done by adding processor.max_cstate=1 to the kernel cmdline for all CPUs.
Additionally Intel CPUs also need intel_idle.max_cstate=0 to fallback to the acpi_idle driver.
How to verify it
Check that processor.max_cstate=1 is present on the cmdline for AMD CPUs
Check that both processor.max_cstate=1 and intel_idle.max_cstate=0 are present on the cmdline for Intel CPUs

#### Why I did it
Currently per-command authorization will check if user is remote user with getpwnam API, which will trigger tacplus-nss for authentication with TACACS server.
But this is not necessary because when user login the user information already add to local passwd file.
