This change of removing hwsku.json is to correct the port index for
sfp ports (Ethernet0, Ethernet1, Ethernet2, Ethernet3) by using
port_config.ini, which should be '1, 2, 3, 4'. We could not do it
with hwsku.json, as it is defined as '5, 5, 5, 5' by platform.json
for the breakout_mode 1x40G[10G].

Fix can't access IPV6 address via management interface because 'default' route table does not add to route lookup issue.
#### Why I did it
When device set with IPV6 TACACS server address, and shutdown all BGP, device can't connect to TACACS server via management interface.
After investigation, I found the IPV6 'default' route table does not add to route lookup:
admin@vlab-01:~$ ip -6 rule list
1001: from all lookup local
32765: from fec0::ffff:afa:1 lookup default
32766: from all lookup main
admin@vlab-01:~$
As compare:
admin@vlab-01:~$ ip -4 rule list
1001: from all lookup local
32764: from all to 172.17.0.1/24 lookup default
32765: from 10.250.0.101 lookup default
32766: from all lookup main
32767: from all lookup default <== 'default' route table exist in IPV4 route lookup
Issue fix by add 'default' route table to route lookup with following command:
admin@vlab-01:~$ sudo ip -6 rule add pref 32767 lookup default
admin@vlab-01:~$ ip -6 rule list
1001: from all lookup local
32765: from fec0::ffff:afa:1 lookup default
32766: from all lookup main
32767: from all lookup default <== 'default' route table been added to IPV6 route lookup
admin@vlab-01:~$

For 40G optics there is SAI handling of T0 facing ports to be set with SR4 type and unreliable los set for a fixed set of ports. For this property to be invoked the requirement is set
phy_unlos_msft=1 in config.bcm.
This change is to meet the requirement and once this property is set, the los/interface type settings is applied by SAI on the required ports.
Why I did it
For Arista-7060CX-32S-Q32 T1, 40G ports RX_ERR minimalization during connected device reboot
can be achieved by turning on Unreliable LOS and SR4 media_type for all ports which are connected to T0.
The property phy_unlos_msft=1 is to exclusively enable this property.

Currently, whenever isc-dhcp-relay forwards a packet upstream,
internally, it will try to send it on a "fallback" interface. My
understanding is that this isn't meant to be a real interface, but
instead is basically saying to use Linux's regular routing stack to
route the packet appropriately (rather than having isc-dhcp-relay
specify specifically which interface to use).
The problem is that on systems with a weak CPU, a large number of
interfaces, and many upstream servers specified, this can introduce a
noticeable delay in packets getting sent. The delay comes from trying to
get the ifindex of the fallback interface. In one test case, it got to
the point that only 2 packets could be processed per second. Because of
this, dhcrelay will easily get backlogged and likely get to a point
where packets get dropped in the kernel.
Fix this by adding a check saying if we're using the fallback interface,
then don't try to get the ifindex of this interface. We're never going
to have an interface named this in SONiC.
