* Parse the rule to see if it is a IP or MAC VLAN flow director rule.

|
|
* UDP/TCP/SCTP PATTERN:
|
|
* The first not void item can be ETH or IPV4 or IPV6
|
|
* The second not void item must be IPV4 or IPV6 if the first one is ETH.
|
|
* The next not void item could be UDP or TCP or SCTP (optional)
|
|
* The next not void item could be RAW (for flexbyte, optional)
|
|
* The next not void item must be END.
|
|
* A Fuzzy Match pattern can appear at any place before END.
|
|
* Fuzzy Match is optional for IPV4 but is required for IPV6
|
|
* MAC VLAN PATTERN:
|
|
* The first not void item must be ETH.
|
|
* The second not void item must be MAC VLAN.
|
|
* The next not void item must be END.
|
|
* ACTION:
|
|
* The first not void action should be QUEUE or DROP.
|
|
* The second not void optional action should be MARK,
|
|
* mark_id is a uint32_t number.
|
|
* The next not void action should be END.
|
|
* UDP/TCP/SCTP pattern example:
|
|
* ITEM Spec Mask
|
|
* ETH NULL NULL
|
|
* IPV4 src_addr 192.168.1.20 0xFFFFFFFF
|
|
* dst_addr 192.167.3.50 0xFFFFFFFF
|
|
* UDP/TCP/SCTP src_port 80 0xFFFF
|
|
* dst_port 80 0xFFFF
|
|
* FLEX relative 0 0x1
|
|
* search 0 0x1
|
|
* reserved 0 0
|
|
* offset 12 0xFFFFFFFF
|
|
* limit 0 0xFFFF
|
|
* length 2 0xFFFF
|
|
* pattern[0] 0x86 0xFF
|
|
* pattern[1] 0xDD 0xFF
|
|
* END
|
|
* MAC VLAN pattern example:
|
|
* ITEM Spec Mask
|
|
* ETH dst_addr
|
|
{0xAC, 0x7B, 0xA1, {0xFF, 0xFF, 0xFF,
|

|
|
* MAC VLAN tci 0x2016 0xEFFF
|
|
* END
|
|
* Other members in mask and spec should set to 0x00.
|
