From: Jakub Kicinski <kuba@kernel.org> Unlike most of our APIs the rx-buf-len param does not have an associated max value. In theory user could set this value pretty high, but in practice most NICs have limits due to the width of the length fields in the descriptors.

The other driver that supports rx_buf_len I think is hns3, and I think you can set the max_rx_buf_len as RX_BUF_LEN_4K there? It only support 2K and 4K. Other than that, looks good to me, Reviewed-by: Mina Almasry <redacted> -- Thanks, Mina
