const std::optional<uint16_t> & rx_threshold ()Rx depth threshold at which the device should be fed new rx buffers.
New buffer notifications from [`NetworkDeviceIfc`] may be skipped while
the number of rx buffers held by the implementation is larger than
`rx_threshold`. It is invalid to provide a value larger than `rx_depth`.
`rx_threshold = rx_depth` is functionally equivalent to `rx_threshold =
rx_depth - 1`.
A large value (close to `rx_depth`) may cause considerable CPU thrash
for small rx completion transaction sizes, while a small value may cause
the implementation to be starved of buffers. The typical choice of value
is `rx_depth / 2`.
