vlanctl command for Broadcom

Set vlan operations interface suffix, if not set ,the default value is "."
    vlanctl --if-suffix      

change real interface name mode,if not set , default mode is RG.
    vlanctl --if <--set-if-mode-rg>|<--set-if-mode-ont>

create vlan operations interface eg. vlanctl --if-create eth0 0 => generate eth0.0 with eth0
    vlanctl --if-create [--routed] [--mcast]
   
create vlan operations interface and specify name
    vlanctl --if-create-name [--routed] [--mcast]

delete vlan operations interface with name
    vlanctl --if-delete

-- NOTIFY start-----------------------------
--------------------------------------------
when create a vlan interface,it will create 10 tables about this vlan interface automatically.
              interface -- -- < 0 tag | 1 tag | 2 tags | 3 tags | 4 tags > 
A tagging rule table determined by and
when a table is created,the default values are set to: TPID(0x8100), pbits(0),vid(1),cfi(0)
and DSCP-TO-PBITS table are set by copying the lowest 3 bits of each DSCP value as the pbits value,
eg. DSCP=5 PBITS=5, DSCP=15 PBITS=7.

-- NOTIFY end-------------------------------

change default actions of a vlan tag rules table,
    vlanctl --if --tags  
        [--default-tpid ] [--default-pbits ] [--default-vid ] [--default-cfi ]

change DSCP to Pbits translation
    vlanctl --if [--cfg-dscp2pbits ]
   
change Tpid table
    vlanctl --if --cfg-tpid  

--------------------------------------------
display a rule table.   eg. vlanctl --if eth0 --rx --tags 0 --show-table
    vlanctl --if --tags --show-table

dispaly DSCP to Pbits table
    vlanctl --if --show-dscp2pbits

display TPID table
    vlanctl --if --show-tpid

display device local stats
    vlanctl --local-stats |

--------------------------------------------
runtest
    vlanctl --run-test

--------------------------------------------

delete all tag rules
    vlanctl --rule-remove-all

delete a tag rule
    vlanctl --if --tags --rule-remove

---------------------------------------------

Add a tag rule
    vlanctl --if --tags [filters] [commads]

     --filter-vlan-dev-mac-addr 0: match all recive frames dest MAC addr against the recive virtual interface
                                                      1: match unicast recive frames dest MAC addr against the recive virtual interface
