This field is used to record the RX queue index for a redirect action
passed via ring_cookie field in struct ethtool_rx_flow_spec which is
a u64 value.
For ex: after adding a filter rule to redirect to a VF using ethtool
# echo 4 > /sys/class/net/p4p1/device/sriov_numvfs
# ethtool -N p4p1 flow-type ip4 src-ip 192.168.0.1 action 0x100000000
querying for the rule shows the Action as 'Direct to queue 0'
# ethtool -n p4p1
4 RX rings available
Total 1 rules
Filter: 2045
Rule Type: Raw IPv4
Src IP addr: 192.168.0.1 mask: 0.0.0.0
Dest IP addr: 0.0.0.0 mask: 255.255.255.255
TOS: 0x0 mask: 0xff
Protocol: 0 mask: 0xff
L4 bytes: 0x0 mask: 0xffffffff
VLAN EtherType: 0x0 mask: 0xffff
VLAN: 0x0 mask: 0xffff
User-defined: 0x0 mask: 0xffffffffffffffff
Action: Direct to queue 0
With this fix, ethtool will report the right queue index even for VFs.
Action: Direct to queue 4294967296
Here 4294967296 corresponds to 0x100000000.
We need to update 'ethtool' to report the queue index as a Hex value so
that it is more user friendly and matches with the 'action' value that
is passed when adding the rule.
