Morten Brørup f0c2dc8201 net: move TCP flags from ethdev header 
TCP flags were moved to the TCP header file from the Ethernet control
header file, and the RTE prefix was added to their names.

Missing TCP ECN flags were added.

The ALL mask did not include TCP ECN flags, so it was renamed to reflect
that it applies to N-tuple filtering only.

Updated other files affected by the renaming accordingly.

/**
* Parse the rule to see if it is a IP or MAC VLAN flow director rule.
* And get the flow director filter info BTW.
* 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,
0x2C, 0x6D, 0x36} 0xFF, 0xFF, 0xFF}
* MAC VLAN tci 0x2016 0xEFFF
* END
* Other members in mask and spec should set to 0x00.
* Item->last should be NULL.
