net: bcmgenet: add support for ethtool rxnfc flows
This commit enables driver support for ethtool commands of this form:
ethtool -N|-U|--config-nfc|--config-ntuple devname
flow-type ether|ip4
[src xx:yy:zz:aa:bb:cc [m xx:yy:zz:aa:bb:cc]]
[dst xx:yy:zz:aa:bb:cc [m xx:yy:zz:aa:bb:cc]] [proto N [m N]]
[src-ip x.x.x.x [m x.x.x.x]] [dst-ip x.x.x.x [m x.x.x.x]] [tos N [m N]]
[l4proto N [m N]] [src-port N [m N]] [dst-port N [m N]] [spi N [m N]]
[l4data N [m N]] [vlan-etype N [m N]] [vlan N [m N]]
[dst-mac xx:yy:zz:aa:bb:cc [m xx:yy:zz:aa:bb:cc]] [action 0] [loc N] |
delete N
Since there is only one Rx Ring in this implementation action 0 behaves no
differently from not specifying a rule.
The rules can be seen with ethtool commands of this form:
ethtool -n|-u|--show-nfc|--show-ntuple devname [rule N]
