0x30 isn't valid for GTP-C, the sequence number must be present in
GTP-C so it will be 0x32 or more. Is this byte actually matched
against by the device using the GTP pctypes?

Why use this value?

This will only match half of GTP-C messages. GTP-C messages have a UDP
port destination of 2123, or a UDP source port of 2123. To match all
GTP-C packets you need to look at both.

This is only valid if v_pt_rsv_flags is 0x30. GTP-U packets are
allowed to have a sequence number, which adds an extra 4 bytes to the
GTP header.

This is only valid if v_pt_rsv_flags is 0x30. GTP-U packets are
allowed to have a sequence number, which adds an extra 4 bytes to the
GTP header.
