net/sched: Allow flower to match on GTP options
Options are as follows: PDU_TYPE:QFI and they refernce to
the fields from the PDU Session Protocol. PDU Session data
is conveyed in GTP-U Extension Header.
GTP-U Extension Header is described in 3GPP TS 29.281.
PDU Session Protocol is described in 3GPP TS 38.415.
PDU_TYPE - indicates the type of the PDU Session Information (4 bits)
QFI - QoS Flow Identifier (6 bits)
