    Problem setting rx ring size using ixgbe on vSphere ESXi 5.1

    SteveCo

      I have a high throughput UDP application running on vSphere 5.1 and I am dropping packets due to rx_dma_no_resources (ethtool -S vmnic4).  I have attempted to change the rx ring buffer size to 4096, but no matter what I do the highest I can seem to get is 456 (according to ethtool -G).  Ethtool says the highest supported value is 4096, so does anyone know how I can increase the ring buffer size to that amount?    I am using driver 3.1.32.

       

      Thanks!
