[LARTC] can use iptables to match 802.1Q P bits?

[swcims]

Hi,All
        I'd like to use iptables to set TOS according to the 802.1Q P bits in ethernet 
header,but I got no idea.You know,we can use this to match mac:iptables -A FORWARD -m 
mac --mac-source 00:e0:4c:3b:b6:d5 -j DROP.So can iptables supply commands to match P 
bits in ethernet header?(If so,I can set:iptables -A FORWARD -p pbits --pbits 0x5 -j 
TOS --set-tos 0xb8.)
        Any suggestion is highly appreciated!
        

        

　　Best regards.
