Hi,

I am using a PowerEdge R660xs with Broadcom BCM57414 NetXtreme-E 10Gb/25Gb RDMA Ethernet Controller. All documentations of the adapter, as well as corresponding kernel module bnxt_en suggest that change of RSS hash keys should be possible. 

We are trying to get a symmetric RSS hash key set for the interfaces with 15 RX channels using:

ethtool -X ens1f0np0 hkey 6D:5A:6D:5A:6D:5A:6D:5A:6D:5A:6D:5A:6D:5A:6D:5A:6D:5A:6D:5A:6D:5A:6D:5A:6D:5A:6D:5A:6D:5A:6D:5A:6D:5A:6D:5A:6D:5A:6D:5A equal 15

However, it always reports with - Cannot set RX flow hash configuration: Operation not supported

I have tried a couple of older kernel versions in vain as well, but not sure if the fault is in the kernel module or the card itself.
