[PATCH 2/2] net/hns3: add FDIR VLAN match mode runtime config

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

The VLAN number in FDIR meta data is used to enable that hardware
bases on VLAN number to strictly match the input flow. And it is
enabled by default.

For the following two rules:
rule0:
      pattern: eth type is 0x0806
      actions: queue index 3
rule1:
      pattern: eth type is 0x0806 / vlan vid is 20
      actions: queue index 4
If enable VLAN number, only the ARP packets with VLAN 20 are directed
to queue 4, and the ARP packets with other VLAN ID cannot be directed
to the specified queue. If app want to all ARP (VLAN or no VLAN)
packets to be directed to the specified queue, app has to set many
rules for VLAN packet. In this case, if driver doesn't enable VLAN
number, app just need to set one rule (rule0).

So this patch adds a "fdir_vlan_match_mode" runtime config which only
can be 'strict' or 'nostrict'. And driver still uses 'strict' mode as
the default mode. Please select 'nostrict' mode if you request all same
ethertype packets with and without VLAN to a specified queue.

[PATCH v2 2/2] net/hns3: add FDIR VLAN match mode runtime config

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

The VLAN number in FDIR meta data is used to enable that hardware
bases on VLAN number to strictly match the input flow. And it is
enabled by default.

For the following two rules:
rule0:
      pattern: eth type is 0x0806
      actions: queue index 3
rule1:
      pattern: eth type is 0x0806 / vlan vid is 20
      actions: queue index 4
If enable VLAN number, only the ARP packets with VLAN 20 are directed
to queue 4, and the ARP packets with other VLAN ID cannot be directed
to the specified queue. If app want to all ARP (VLAN or no VLAN)
packets to be directed to the specified queue, app has to set many
rules for VLAN packet. In this case, if driver doesn't enable VLAN
number, app just need to set one rule (rule0).

So this patch adds a "fdir_vlan_match_mode" runtime config which only
can be 'strict' or 'nostrict'. And driver still uses 'strict' mode as
the default mode. Please select 'nostrict' mode if you request all same
ethertype packets with and without VLAN to a specified queue.

As it is done in the rest of the document, you should use double backquotes
for values of the devargs.

[PATCH v3 0/2] net/hns3: add FDIR VLAN match mode runtime config

[Dongdong Liu]

This patchset contains two patches:
The first one is to delete duplicate macro definition for hns3.
The second one is to add FDIR VLAN match mode runtime config for hns3

v2->v3:
-  Use double backquotes for values of the devargs and fix spelling errors.

v1->v2:
- Fix the hns3.rst doc build warining.

[PATCH v3 2/2] net/hns3: add FDIR VLAN match mode runtime config

[Dongdong Liu]

From: Huisong Li <lihuisong@huawei.com>

The VLAN number in FDIR meta data is used to enable that hardware
bases on VLAN number to strictly match the input flow. And it is
enabled by default.

For the following two rules:
rule0:
      pattern: eth type is 0x0806
      actions: queue index 3
rule1:
      pattern: eth type is 0x0806 / vlan vid is 20
      actions: queue index 4
If enable VLAN number, only the ARP packets with VLAN 20 are directed
to queue 4, and the ARP packets with other VLAN ID cannot be directed
to the specified queue. If app want to all ARP (VLAN or no VLAN)
packets to be directed to the specified queue, app has to set many
rules for VLAN packet. In this case, if driver doesn't enable VLAN
number, app just need to set one rule (rule0).

So this patch adds a "fdir_vlan_match_mode" runtime config which only
can be 'strict' or 'nostrict'. And driver still uses 'strict' mode as
the default mode. Please select 'nostrict' mode if you request all same
ethertype packets with and without VLAN to a specified queue.

'::' doesn't provide pre-formatted text without an empty line after it,
I will fix this while merging, but other device argument documentations
have same problem, can you please send a patch to fix it?
