These are some of the basic/common commands used for adding, removing and managing ntuple rules.
Note in the below examples I am using the interface name enp5s0f0; replace that with the relevant interface you are using.
# ethtool -k enp5s0f0 | grep ntuple
ntuple-filters: on
ethtool -K enp5s0f0 ntuple on
ethtool -K enp5s0f0 ntuple off
ethtool -S enp5s0f0 | grep fdir
ethtool -u enp5s0f0
ethtool -U enp5s0f0 flow-type <type> src-ip <ip> [m <ip_mask>] dst-ip <ip>
[m <ip_mask>] src-port <port> [m <port_mask>] dst-port <port> [m <port_mask>]
action <queue>
ethtool -U enp5s0f0 delete <N>
The output of ethtool --help gives a list of options available:
