After multiple times of cable failover and failback on trunk ports, Link/Activity
LEDs of trunk ports are malfunctioning.
In the V126.96.36.199, the "value" of the if index is pass to the API,
SWCTRL_TrunkIDToLogicalPort. This is wrong. It should pass "address" of the ifindex to
this API. Otherwise the ifindex will not get the correct value and if the ifindex is
equal to zero, then the following API, VLAN_MGR_IsPortVlanMember will have some trouble.
It will try to use an illegal value as index of array and this will cause "exception".
When this happen, the local console will display some exception message and the LED will
Add a "&" before the ifindex. Also add more code to make sure when the ifindex is
not in the correct range, it will not go on to call VLAN_MGR_IsPortVlanMember.
Problem: A typo as described below: "Failed to remove untaged list on ethernet 1/7",
"untaged" misses a "g". It should be "untagged".
Root cause: typo.
Fix: Correct the "untaged" into "untagged"

A client couldn't ping server blades through either static or LACP trunk after LOM
was disabled and re-enabled in the case of Windows OS.
In static/LACP trunk configuration, the previous version (v184.108.40.206)
did not add the trunk ports into the MultiPortMap. Because of this, the switch didn't allow
arp or other broadcast types of packets to be sent to the trunk ports. When the server LOM
was disabled and re-enabled, it's arp table got cleared up, the server LOM could still
receive the ICMP ping request, since it didn't know the client's mac after re-enabled, it
sent out arp, but couldn't get reply due to the cause stated. Hence, the client ping timed
Added the trunk ports into the MultiPortMap.

If an Ethernet frame with source MAC address of all FFFF's was learned by the switch,
the multicast map table was changed. This caused loss of network connectivity to
server blade. The source of the illegal fames is not generated by this switch blade. It is
generated somewhere of the outside network.
This is a chip-level issue within the switching controller ASIC B5632/33 Ax
stepping family. An ingress packet with MACSA = multicast/broadcast, the packet
address is learnt as a unicast frame. Hence, when aging is enabled, a time stamp
(TSTAMP) field gets erroneously appended to the Destination Port field to create the
multicast bitmap. The time stamp field is initialized to all 0's. When the entry is
statistic, the time stamp field remains 0's that causes some bits, which represent
switch ports, are 0's. Those ports with 0's will be excluded from the
broadcast/multicast and not receive the broadcast/multicast packets.
Added codes in firmware to periodically monitor multicast map table of the
switch. When the multicast map table is changed, the firmware re-programs the
right value back and overwrite the wrong table.

The Link LEDs were always on no matter link existed or not as long as switch
In the LED driver, a data structure needs to use UI16_T instead of UI8_T.
Otherwise the data sent to the lower layer EPLD was incorrect.
Use the right function UI16_T.
