Since the input set hint is the supper set, so I suppose you use the supper set "ETH_RSS_IPV4 | ETH_RSS_GTPC" here, and considerate if we need to enable GTPC hash at this patch,
if not it  could be process when parsing pattern. Want to know other's opinion.

I think this patch will not cover outer IP hash for any GTPU case, only none-inner GTPU case, right?

I still not funs of set field to zero here since it should be general use for other case, it could specific refine to 0 when parsing pattern if need.

There is also a question the same as the other mail loop of GTPC, should it be supper set here?

In V1 patch I have put TEID field as input set, but the kernel driver did not supported this field and returned success.
That's mean the rule has been created succeed, but it did not work.

As above, if user really set ETH_RSS_GTPU as input set, the rule will be created succeed, but it don't work.

In V1 patch I have put TEID field as input set, but the kernel driver did not supported this field and returned success.
That's mean if user really set ETH_RSS_GTPC as input set, the rule will be created succeed, but it don't work

Its better to also check phint for outer case, could be implemented as below

If (inner) {
	Shift 
	Hdr = hdrs[0]
}
else {
	Hdr = hdrs[count]
}

hdr-count++

if (phint & IAVF_PHINT_GTPU_EH_DWN)
	VIRTCHNL_SET_PROTO_HDR_TYPE(hdr1, GTPU_EH_PDU_DWN);
else if (phint & IAVF_PHINT_GTPU_EH_UP)

[dpdk-dev] [PATCH v6] net/iavf: support outer IP hash for no inner GTPU

[alvinx.zhang]

From: Alvin Zhang <alvinx.zhang@intel.com>

Outer IP hash can be configured as input sets for no inner GTPU packets.

Signed-off-by: Alvin Zhang <alvinx.zhang@intel.com>

V2: Modify codes according to comments.
V3: Refact all codes.
V4: Fix compatibility issues.
V5, V6: Modify codes according to comments.
