Haiyue Wang 1f70dfc542 iavf: redefine the magic number for FDIR GTP-U header fields 
The flex-byte for GTP-U protocol header fields uses the magic number,
which is hard to maintain and understand, define the interested fields
with meaningful macro name, based on the GTP-U protocol stack:

GTP-U header
     +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
     | 0x1 |1|0|1|0|0|     0xff      |           Length              |
     +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
     |                           TEID = 1654                         |
     +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
     |    Sequence Number = 0        |N-PDU Number=0 |NextExtHdr=0x85|
     +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

GTP-U Extension Header (PDU Session Container)
     +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
     |  ExtHdrLen=2  |Type=0 | Spare |0|0|   QFI     | PPI |  Spare  |
     +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
     |                    Padding                    |NextExtHdr=0x0 |
     +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
