size ( MAX_DESCRIPTORS + 1 = 4096)
This will make the circular buffer macros happy but question is that do
we actually have that many descriptor buffers?

That's why we have to pass MAX_DESCRIPTORS + 1 so that it works
when the Macros does a size - 1
Isn't that incorrect to do that, pretending to have more descriptors
than we ac

For some reason arguments to most of the circular buffers
macros are used in reverse, tail is used for head and vice versa.
This leads to bam thinking that there is an extra descriptor at the
end and leading to retransmitting descriptor which was not scheduled
by any driver. This happens after MAX
