-+ help
-+ This optoin enables the Emulated rdtsc support for MIPS, which allows
-+ the user-space applications read the R4k count directly. Currently,
-+ this only support the CONFIG_MIPS32_O32 and R4K, but future, we may
-+ add support for scall64-{n32,64}.S and scall32-32.S and for the count
-+ registers provided by the other MIPS variants.
-+
-+ This emulation based on the syscall instruction, by default, the
-+ syscall is encoded as 0x0000000c, except the 0xc, the other parts can
-+ be encoded as specific meaning. when a syscall instruction is issued,
-+ through checking the encoding of the instruction, when the encoding
-+ is the generic 0x000000c, we do the generic syscall work, if
-+ something other is encoded in, we can do relevant things, except for
-+ the light-weight things, such as read a register. herein, we read the
-+ count register whenever there is something encoded in the syscall
-+ instruction. In the future, we may be possible to abstract more
-+ light-weight & frequently-used operations and add a
-+ sys_call_table-like table to store the entries of some light-weight
-+ operations and encode 1,2,3... into the syscall instruction and jump
-+ to respective entry for diffrent numbers, as a result, we get
-+ fast-syscall and which may speed up the user-space applications and
-+ even be possibly improve the determinism.

-+ * -> FIFO is where the incoming and outgoing data is placed
-+ * -> TRTG is the unit that pulls the data from the FIFO for Tx and pushes

-+ * -> TMAC is the outgoing MAC interface and RMAC is the incoming.
