    Unable to change NIC settings with ethtool

    Hi all,

    I'm trying to change my NIC (Intel 10G NIC) settings using ethtool, but can't seem to do that.

    I tried

    ethtool -G xge0 rx 32768 tx 32768
    and then tried to see if the settings have changed using

    ethtool -g xge0
    But I see the output

    Ring parameters for xge0: 
    Pre-set maximums: 
    RX:        4096 
    RX Mini:   0 
    RX Jumbo:  0 
    TX:        4096 
    Current hardware settings: 
    RX:        4096 
    RX Mini:   0 
    RX Jumbo:  0 
    TX:        4096
    Why can't I change the settings?

    Thank you.

    1. are you root?

    2. some NICs don't support changing some settings. check the output of dmesg for hardware messages, after running ethtool.
