Flags	Meaning
0x1	Some kind of priority that helps to select to which packet list the packet is inserted into.
0x100	Do not insert packet checksum (at tx_buf[2 + len]), where len = tx_buf[2]. And don't memset the rest of the buffer to -1 (memset(tx_buf + len + 3, -1, 29 - len)) if len < 29.
0x400	When set, use rx_extra to receive the data. rx_extra_size must be greater than 32.
0x800	When set: use tx_extra instead of tx for sending data. The size is contained in tx_extra[2] and must be smaller or equal to 253. When cleared: use tx and the size is contained in tx[2], which has to be smaller or equal 29.

The type argument determines what to do.

Real define names are like: "SCE_SYSCON_POWERMODE_MODE_STANDBY".
