Looks like changing the share code. Or like :

	ret = i40e_init_adminq(hw);
	if (ret != I40E_SUCCESS) {
		PMD_INIT_LOG(ERR, "Failed to init adminq: %d", ret);
		return -EIO;
	}
	...
	clear I40E_HW_FLAG_802_1AD_CAPABLE here ...

Yes, it's better to clear this flag in case it will be used in other place.

[dpdk-dev] [DPDK] net/i40e: fix SFP X722 not work with FW4.16

[Xiao Zhang]

FW4.16 of SFP X722 does not support setting TPID by set_switch_config
adminq operation, for firmware version less than 4.16 TPID is set by
register instead. Follow the same path with new firmware version for
SFP X722 to make it work.

[dpdk-dev] [v2] net/i40e: fix SFP X722 not work with FW4.16

[Xiao Zhang]

FW4.16 of SFP X722 does not support setting TPID by set_switch_config
adminq operation, for firmware version less than 4.16 TPID is set by
register instead. For device SFP X722, disable adminq flag to follow
the same path with old firmware version to make it work.

Signed-off-by: Xiao Zhang <xiao.zhang@intel.com>

v2
Unset adminq flag instead of only checking device id when set TPID.
v1
Check device id when setting TPID, use adminq if not SFP X722, else
use register.

The commit log says some version like FW4.16 doesn't support ADQ, but this line
of code means all FW doesn't support ADQ. Which one is right ? :-)

Old versions do not support ADQ and did not use ADQ operation in the code. And new FW with version 4.16 also does not support ADQ neither but used the ADQ operation in the code.
So all FW of SFP X722 do not support ADQ, the commit log may be confuse, I will make it more clear.

[dpdk-dev] [v3] net/i40e: fix SFP X722 not work with FW4.16

[Xiao Zhang]

set_switch_config adminq operation was used to set TPID for SFP X722
with FW4.16, but adminq is not supported which lead to failure. Since
all FW versions of SFP X722 do not support adminq, disable adminq flag
to use resigter setting to make it work.

Check device id when setting TPID, use adminq if not SFP X722, else

[dpdk-dev] [v4] net/i40e: fix SFP X722 not work with FW4.16

[Xiao Zhang]

The code checked the NVM API version of FW to check if support adminq 
operation, when version is 1.7 or above adminq operation is support 
and the adminq flag will be set. The code will use adminq to set TPID if
the flags set or to use register. The NVM API version of SFP X722 old
versions are lowwer than 1.7 and for FW4.16 is 1.8. But FW4.16 of SFP
X722 does not support adminq operation, the legacy logic is not compatible
with device SFP X722 currently. Check the device id to unset adminq
flag to use resigter setting to make it work.

Sorry, I'm still confused about what this patch is doing. From the commit message it seems like there are a couple of conditions:

If the device is X722
	Then if FW < 1.7 then use register to set TPID
	Else use adminq to set TPID

The change in the code is only looking to see if the device is X722 and not doing any other checking of FW version.

Am I misunderstanding the commit message, the patch, or both?

I have updated the commit log while merging [1] (according what I understand) I
hope it is more clear.

[1]
    net/i40e: fix SFP X722 with FW4.16

    When NVM API version is 1.7 or above adminq operation to set TPID is
    set as supported. This cause using adminq instead of registers.

    For SFP X722 FW4.16, reported NVM API version is 1.8, and this cause
    adminq operation to set as supported but it is not supported on FW4.16

    Additional check added for SFP X722 to not enable adminq operation.

Thanks Ferruh for updating the log. 

There are two versions here, NVM API version and FW version.
For SFP X722, NVM API version of FW4.16 is 1.8, old versions bellow 1.7.(eg. FW4.0 with NVM API 1.6).
The adminq operation is not workable for FW4.16, so all FW versions do not work with adminq operation for SFP X722 currently. So add device check for SFP X722 in this fix.
