Hello, This patch fixes an issue with my ConnectX5 NIC (15b3:1019) showing 65535 as the maximum number of RX descriptors.
So, a disclaimer: I don't know whether other NICs (ConnectX6?) allow larger values. The value of 8192 was obtained experimentally with ethtool: ethtool -G *nic* rx 8192, as I do not have the NIC programmer's manual. Using anything larger than 8192 resulted in an error. Similarly, anything in the [8193, 32768) range with the DPDK PMD results in an rx queue allocation failure.
