[dpdk-stable] patch 'net/hns3: fix filter parsing comment' has been queued to stable release 19.11.10

[christian.ehrhardt@canonical.com]

Hi,

FYI, your patch has been queued to stable release 19.11.10

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/12/21. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/c5f7acac593f4b3358d3d2c449870f11d65114a5

Thanks.

 /*
- * Parse the rule to see if it is a IP or MAC VLAN flow director rule.
- * And get the flow director filter info BTW.
- * UDP/TCP/SCTP PATTERN:
- * The first not void item can be ETH or IPV4 or IPV6
- * The second not void item must be IPV4 or IPV6 if the first one is ETH.
- * The next not void item could be UDP or TCP or SCTP (optional)
- * The next not void item could be RAW (for flexbyte, optional)
- * The next not void item must be END.
- * A Fuzzy Match pattern can appear at any place before END.
- * Fuzzy Match is optional for IPV4 but is required for IPV6
- * MAC VLAN PATTERN:
- * The first not void item must be ETH.
- * The second not void item must be MAC VLAN.
- * The next not void item must be END.
- * ACTION:
- * The first not void action should be QUEUE or DROP.
- * The second not void optional action should be MARK,
- * mark_id is a uint32_t number.
- * The next not void action should be END.
- * UDP/TCP/SCTP pattern example:
- * ITEM		Spec			Mask
- * ETH		NULL			NULL
- * IPV4		src_addr 192.168.1.20	0xFFFFFFFF
- *		dst_addr 192.167.3.50	0xFFFFFFFF
- * UDP/TCP/SCTP	src_port	80	0xFFFF
- *		dst_port	80	0xFFFF
- * END
- * MAC VLAN pattern example:
- * ITEM		Spec			Mask
- * ETH		dst_addr
-		{0xAC, 0x7B, 0xA1,	{0xFF, 0xFF, 0xFF,
-		0x2C, 0x6D, 0x36}	0xFF, 0xFF, 0xFF}
- * MAC VLAN	tci	0x2016		0xEFFF
- * END
- * Other members in mask and spec should set to 0x00.
- * Item->last should be NULL.
+ * Parse the flow director rule.
+ * The supported PATTERN:
+ *   case: non-tunnel packet:
+ *     ETH : src-mac, dst-mac, ethertype
+ *     VLAN: tag1, tag2
+ *     IPv4: src-ip, dst-ip, tos, proto
+ *     IPv6: src-ip(last 32 bit addr), dst-ip(last 32 bit addr), proto
+ *     UDP : src-port, dst-port
+ *     TCP : src-port, dst-port
+ *     SCTP: src-port, dst-port, tag
+ *   case: tunnel packet:
+ *     OUTER-ETH: ethertype
+ *     OUTER-L3 : proto
+ *     OUTER-L4 : src-port, dst-port
+ *     TUNNEL   : vni, flow-id(only valid when NVGRE)
+ *     INNER-ETH/VLAN/IPv4/IPv6/UDP/TCP/SCTP: same as non-tunnel packet
+ * The supported ACTION:
+ *    QUEUE
+ *    DROP
+ *    COUNT
+ *    MARK: the id range [0, 4094]
+ *    FLAG
+ *    RSS: only valid if firmware support FD_QUEUE_REGION.
