**- Why I did it**
For decoding system EEPROM of S6000 based on Dell offset format and S6000-ON’s system EEPROM in ONIE TLV format.
**- How I did it**
- Differentiate between S6000 and S6000-ON using the product name available in ‘dmi’ ( “/sys/class/dmi/id/product_name” )
- For decoding S6000 system EEPROM in Dell offset format and updating the redis DB with the EEPROM contents, added a new class ‘EepromS6000’ in eeprom.py,
- Renamed certain methods in both Eeprom, EepromS6000 classes to accommodate the plugin-specific methods.
**- How to verify it**
- Use 'decode-syseeprom' command to list the system EEPROM details.
- Wrote a python script to load chassis class and call the appropriate methods.

Fix hostcfgd so that changes to the "FEATURE" table in ConfigDB are properly handled. Three changes here:
1. Fix indenting such that the handling of each key actually occurs in the for key in status_data.keys(): loop
2. Add calls to sudo systemctl mask and sudo systemctl unmask as appropriate to ensure changes persist across reboots
3. Substitute returns with continues so that even if one service fails, we still try to handle the others
Note that the masking is persistent, even if the configuration is not saved. We may want to consider only calling systemctl enable/disable in hostcfgd when the DB table changes, and only call systemctl mask/unmask upon calling config save.
* Run fsck filesystem check support prior mounting filesystem
If the filesystem become non clean ("dirty"), SONiC does not run fsck to
repair and mark it as clean again.
This patch adds the functionality to run fsck on each boot, prior to the
filesystem being mounted. This allows the filesystem to be repaired if
needed.
Note that if the filesystem is maked as clean, fsck does nothing and simply
return so this is perfectly fine to call fsck every time prior to mount the
filesystem.
How to verify this patch (using bash):
Using an image without this patch:
Make the filesystem "dirty" (not clean)
[we are making the assumption that filesystem is stored in /dev/sda3 - Please adjust depending of the platform]
[do this only on a test platform!]
dd if=/dev/sda3 of=superblock bs=1 count=2048
printf "$(printf '\\x%02X' 2)" | dd of="superblock" bs=1 seek=1082 count=1 conv=notrunc &> /dev/null
dd of=/dev/sda3 if=superblock bs=1 count=2048
Verify that filesystem is not clean
tune2fs -l /dev/sda3 | grep "Filesystem state:"
reboot and verify that the filesystem is still not clean
Redo the same test with an image with this patch, and verify that at next reboot the filesystem is repaired and becomes clean.
fsck log is stored on syslog, using the string FSCK as markup.
**- Why I did it**
- Skip thermalctld in DellEMC S6000, S6100, Z9100 and Z9264 platforms.
- Change the return type of thermal Platform APIs in DellEMC S6000, S6100 and Z9100 platforms to 'float'.
**- How I did it**
- Add 'skip_thermalctld:true' in pmon_daemon_control.json for DellEMC S6000, S6100, Z9100 and Z9264 platforms.
- Made changes in thermal.py, for 'get_temperature', 'get_high_threshold' and 'get_low_threshold' to return 'float' value.
**- How to verify it**
- Check thermalctld is not running in 'pmon'.
- Wrote a python script to load Chassis class and then call the APIs accordingly and verify the return type.

This change allows the recursive `git clean` and `git reset` commands to continue even if they encounter an error in one of the submodules. Previously, if an error was encountered, the operation would terminate with a message similar to the following:
Stopping at 'src/sonic-mgmt-framework'; script returned non-zero status.
I found that with IPv4Network types, calling list(ip_ntwrk.hosts()) is reliable. However, when doing the same with an IPv6Network, I found that the conversion to a list can hang indefinitely. This appears to me to be a bug in the ipaddress.IPv6Network implementation. However, I could not find any other reports on the web.
This patch changes the behavior to call next() on the ip_ntwrk.hosts() generator instead, which returns the IP address of the first host.
Since the introduction of VRF, interface-related tables in ConfigDB will have multiple entries, one of which only contains the interface name and no IP prefix. Thus, when iterating over the keys in the tables, we need to ignore the entries which do not contain IP prefixes.
Modified caclmgrd behavior to enhance control plane security as follows:
Upon starting or receiving notification of ACL table/rule changes in Config DB:
1. Add iptables/ip6tables commands to allow all incoming packets from established TCP sessions or new TCP sessions which are related to established TCP sessions
2. Add iptables/ip6tables commands to allow bidirectional ICMPv4 ping and traceroute
3. Add iptables/ip6tables commands to allow bidirectional ICMPv6 ping and traceroute
4. Add iptables/ip6tables commands to allow all incoming Neighbor Discovery Protocol (NDP) NS/NA/RS/RA messages
5. Add iptables/ip6tables commands to allow all incoming IPv4 DHCP packets
6. Add iptables/ip6tables commands to allow all incoming IPv6 DHCP packets
7. Add iptables/ip6tables commands to allow all incoming BGP traffic
8. Add iptables/ip6tables commands for all ACL rules for recognized services (currently SSH, SNMP, NTP)
9. For all services which we did not find configured ACL rules, add iptables/ip6tables commands to allow all incoming packets for those services (allows the device to accept SSH connections before the device is configured)
10. Add iptables rules to drop all packets destined for loopback interface IP addresses
11. Add iptables rules to drop all packets destined for management interface IP addresses
12. Add iptables rules to drop all packets destined for point-to-point interface IP addresses
13. Add iptables rules to drop all packets destined for our VLAN interface gateway IP addresses
14. Add iptables/ip6tables commands to allow all incoming packets with TTL of 0 or 1 (This allows the device to respond to tools like tcptraceroute)
15. If we found control plane ACLs in the configuration and applied them, we lastly add iptables/ip6tables commands to drop all other incoming packets
For detecting transceiver change events through xcvrd in DellEMC S6000, S6100 and Z9100 platforms.
- In S6000, rename 'get_transceiver_change_event' in chassis.py to 'get_change_event' and return appropriate values.
- In S6100, implement 'get_change_event' through polling method (poll interval = 1 second) in chassis.py (Transceiver insertion/removal does not generate interrupts due to a CPLD bug)
- In Z9100, implement 'get_change_event' through interrupt method using select.epoll().

* Address Review Comments of using pyhton based config load_minigraph/
config save/config reload from shell scripts so that we don't duplicate

done by those commands.

* Adding new BGP peer groups PEER_V4_INT and PEER_V6_INT. The internal BGP sessions
will be added to this peer group while the external BGP sessions will be added
to the exising PEER_V4 and PEER_V6 peer group.
* Check for "ASIC" keyword in the hostname to identify the internal neighbors.
