[PATCH net-next 02/20] net: hns3: Disable VFs change rxvlan offload status

[Peng Li]

From: Jian Shen <shenjian15@huawei.com>

Rxvlan offload status can only be changed by PF. Initialize
the value of NETIF_F_HW_VLAN_CTAG_RX bit of hw_features for
VFS to false, make sure user can't be able to change it.

[PATCH net-next 03/20] net: hns3: Unify the strings display of packet statistics

[Peng Li]

From: Jian Shen <shenjian15@huawei.com>

Some members of packet statistics are named in different styles.
This patch unifies them with new internal name rules, the main
modification are below:
trans --> tx
rcv --> rx
rcb_q%d_tx -->  txq#%d
rcb_q%d_rx -->  rxq#%d
sw_err_cnt(tx side) --> tx_dropped
sw_err_cnt(rx side) --> rx_dropped
pkts --> packets
tx_err_cnt --> errors
rx_err_cnt --> errors

[PATCH net-next 06/20] net: hns3: Modify the update period of packet statistics

[Peng Li]

From: Jian Shen <shenjian15@huawei.com>

It takes more than 200 query response messages between
driver and IMP, while updating the packet statistics.
It's too heavy for IMP to update it per second.

Extend the update period of packet statistics data from
1 second to 300 seconds(if too long, the statistics may
overflow).

As a result, we need to update it while querying with
ifconfig tool to keep the statistics data fresh.

There is something odd going on with patch here. Notice how it says
hns3_nic_set_features(). This is not the function being patched, it is
actually the next one, hns3_nic_get_stats64(), which makes a lot more
sense.

Is it because the static void is on the previous line?

It would be nice if the function was correctly reported. It makes it
easier to review the patch.

Yes, it is because the static void is on the previous line.

I can add one patch to fix the  previous line ,  and this patch will 
correct  automatically.

do it need V2 patchset? or push a new patch after this patchset?

Thanks for looking into this. This actually seems like a patch bug,
but i think the consensus is to have the function type on the same
line as the function name within Linux.

No need for a v2. Just send followup patches.

When NIC is down, mask the packet statistics for querying

Ugh, I so didn't review this in time :(  I think there is a consensus
that we should avoid duplicating standard stats in ethtool.  Especially
those old ones.  Like "collisions", I assume this is a modern NIC, are
collisions still a thing?

There is no standard way to get per-queue values, and ethtool stats are
how pretty much every driver provides it.

Right, agreed.  I'm only objecting to this patch (12/20), where we can
see the telltale code like this:

+	const struct rtnl_link_stats64 *net_stats;
+	struct rtnl_link_stats64 temp;
+
+	net_stats = dev_get_stats(netdev, &temp);
+	for (i = 0; i < HNS3_NETDEV_STATS_COUNT; i++) {
+		stat = (u8 *)net_stats + hns3_netdev_stats[i].stats_offset;
+		*data++ = *(u64 *)stat;
+	}

Where:

+#define HNS3_NETDEV_STAT(_string, _member)	{			\
+	.stats_string = _string,					\
+	.stats_offset = offsetof(struct rtnl_link_stats64, _member)	\
+}
+

+	/* Rx per-queue statistics */
+	HNS3_NETDEV_STAT("rx_packets", rx_packets),
+	HNS3_NETDEV_STAT("tx_packets", tx_packets),

etc.  IOW dumping struct rtnl_link_stats64 to ethtool -S member by
member.

Let me put the netlink per-queue stats on my soft TODO list :)

Oh, I only noticed this extra misleading comment now.  Unless each queue
has a netdev, I don't see how these are per-queue.

[patch 12/20 ] add statistics of netdev for ethtool -S, netdev may have 
multi queue.

As discussion here,  it is duplicate to add this patch.


I revert  [patch 12/20 ] , and then test on my board, HNS3 basic function and ethtool -S work well.

So I think it is OK if you can revert  [patch 12/20 ]("net: hns3: Add packet statistics of netdev").

[PATCH net-next 14/20] net: hns3: fix for updating fc_mode_last_time

[Peng Li]

From: Fuyun Liang <liangfuyun1@huawei.com>

commit a9c782822166 ("net: hns3: add support for set_pauseparam")
adds set_pauseparam support for ethtool cmd, but forgets to update
fc_mode_last_time when PFC mode is disabled in hclge_cfg_pauseparam().
The wrong fc_mode_last_time will be used to update flow control mode
when lldpad has been running. As a result, when using the ethtool
command "-a", user will get a wrong pause parameter.

This patch adds the fc_mode_last_time update when PFC mode is disabled.

[PATCH net-next 15/20] net: hns3: fix for setting MTU

[Peng Li]

From: Fuyun Liang <liangfuyun1@huawei.com>

When setting MTU, actually what we do is configuring the max frame size
for the hardware. ETH_HLEN、ETH_FCS_LEN and VLAN_HLEN must need to be
considered. And the frame size which is less than the default value
should not be set to the hardware. Because in the hardware, the the max
frame size not only controls the RX packet size, but also controls the
TX packet size. the RX packets whose size are greater than the setting
value will be dropped.

This patch fixes the bug setting a error max frame size to hardware.

Pause parameters include source address, transmit gap and pause time.
The default value of the pause source address is zero in the hardware.
Default pause parameters need to be set to the hardware. Also, when
setting new mac address, the pause source address need to be updated.
