Both second and third are HV_GPADL_RING type. One is send ring and the
other is receive ring. The driver keeps the order to allocate rx and
tx buffer. You are right this is not robust and will add a mutex to keep
the order.

Or you introduce fixed indexes for the RX and TX buffers?

The interface just allocates a buffer and driver will continue to configure the buffer to be rx or tx after calling.
