Am not able to set Combined channels for a SRIOV VF on ConnectX-5 MT27800 Controller card.
For a PF it is showing as shown below as :
ethtool -l p4p1
Channel parameters for p4p1:
Pre-set maximums:
RX: 0
TX: 0
Other: 512
Combined: 48
Current hardware settings:
RX: 0
TX: 0
Other: 0
Combined: 48
[root@dhcp-10-123-66-250 ~]#
For a VF spawned for above interface(p4p1):
ethtool -l p4p1_0
Channel parameters for p4p1_0:
Pre-set maximums:
RX: 0
TX: 0
Other: 512
Combined: 7
Current hardware settings:
RX: 0
TX: 0
Other: 0
Combined: 7
For a VF, it is showing max 7 combined channels , i need to set more than 7 up to 16 , is it possible? if so how to set it if not what is the reason.
