Public bug reported:
This is a backport request from Netronome for Ubuntu 18.04 LTS
This patchset corrects the following behaviour:
1. Add TC filter to hardware while hw-tc-offload is on
2. Switch hw-tc-offload to off using ethtool
3. Filters added to hardware in step 1 are still active but can no longer be
removed.
The upstream solution to this problem is to prohibit switching hw-tc-
offload to off when filters are present in hardware.
The upstream commits, accepted for v4.16, are:
d692403e5cf8 (“nfp: forbid disabling hw-tc-offload on representors while
offload active”)
0b9de4ca853b (“nfp: don't advertise hw-tc-offload on non-port netdevs”)
e3ac6c0737e2 (“nfp: bpf: require ETH table”)
** Affects: linux (Ubuntu)
Importance: Undecided
