[PATCH net-next 02/10] net: hns3: Set extra mac address of pause param for HW

[Salil Mehta]

From: Fuyun Liang <liangfuyun1@huawei.com>

The extra mac address of pause param is used to do double check
for pause frame. This patch set it to HW. If we do not do that,
pfc pause frame will be transferred protocol stack when normal
flow control mode is enabled.

[PATCH net-next 03/10] net: hns3: Rename loop mode

From: Fuyun Liang <liangfuyun1@huawei.com>

Our loop mode includes mac loop, serdes loop and phy loop. Not all of them
are related with mac. This patch corrects their names.

[Salil Mehta]

loopback now. Current name is wrong. This patch renames mac loopback to
app loopback.

[PATCH net-next 06/10] net: hns3: Fix for packet buffer setting bug

[Salil Mehta]

From: Yunsheng Lin <linyunsheng@huawei.com>

The hardware expects a unit of 128 bytes when setting
packet buffer. When calculating the packet buffer size,
hclge_rx_buffer_calc does not round up the size as a unit
of 128 byte, which may casue packet lost problem when stress
testing.

This patch fixes it by rounding up packet size when calculating.

[PATCH net-next 07/10] net: hns3: Fix for netdev not up problem when setting mtu

[Salil Mehta]

From: Yunsheng Lin <linyunsheng@huawei.com>

Currently hns3_nic_change_mtu will try to down the netdev before
setting mtu, and it does not up the netdev when the setting fails,
which causes netdev not up problem.

This patch fixes it by not returning when the setting fails.

[PATCH net-next 09/10] net: hns3: Modify hns3_get_max_available_channels

[Salil Mehta]

From: Huazhong Tan <tanhuazhong@huawei.com>

The current hns3_get_max_available_channels returns the total number
of queues for the device, which makes ethtool -L set the number of queues
per channel queues incorrectly, so hns3_get_max_available_channels should
return the maximum available number of queues per channel, depending on
the total number of queues allocated and the hardware configurations.

[PATCH net-next 10/10] net: hns3: Fix loss of coal configuration while doing reset

[Salil Mehta]

From: Huazhong Tan <tanhuazhong@huawei.com>

The user's coal configuration will be lost after reset, so the tx_coal
and rx_coal fields are added to the struct hns_nic_priv to save the coal
configuration and used to restore the user's configuration after the reset
is complete.

Fixes: bb6b94a896d4 ("net: hns3: Add reset interface implementation in client")

RE: [PATCH net-next 00/10] Cleanups, minor additions & fixes for HNS3 driver

[Salil Mehta]

Hi David/Eric,
I missed to include a patch during a patch-set submission which caused some build errors. 
I have fixed that in V2 version of this patch-set. 

The only change between V1-->V2 is in patch:
 "hns3: Add serdes parallel inner  loopback support"

This also fixes the spelling mistake identified by David and error shown
by Eric Dumazet.

Sorry for any in convenience caused.

Thanks & regards
