Sudarsana, let me ask you something: why does the register is reading
value 0x0 always in the
TX timestamp routine if the RX filter is set to None? This is the main
cause of the thread reschedule
thing.

Of course this thread thing is important to fix, but I was discussing
with my leader here and we
are curious on the reasoning the register is getting 0x0.

Thanks in advance,

Guilherme
