[PATCH net-next 0/5] fix some bugs for HNS3

[Peng Li]

This patchset fixes some bugs for HNS3 driver:
[Patch 1/5 - 2/5] fix 2 return vlaue issues.
[Patch 3/5 - 4/5] fix 2 comments reported by code review.
[Ptach 5/5] avoid sending message to IMP because IMP will not
handle any message when it is resetting.

[PATCH net-next 1/5] net: hns3: fix for returning wrong value problem in hns3_get_rss_key_size

[Peng Li]

From: Fuyun Liang <liangfuyun1@huawei.com>

The return type of hns3_get_rss_key_size is u32. But a negative value is
returned. This patch fixes it by replacing the negative value with zero.

[PATCH net-next 3/5] net: hns3: fix for the wrong shift problem in hns3_set_txbd_baseinfo

[Peng Li]

From: Fuyun Liang <liangfuyun1@huawei.com>

Third parameter of hnae_set_field is shift, But a mask is given. This
patch fixes it by replacing HNS3_TXD_BDTYPE_M with HNS3_TXD_BDTYPE_S.

[PATCH net-next 4/5] net: hns3: fix for not initializing VF rss_hash_key problem

[Peng Li]

From: Fuyun Liang <liangfuyun1@huawei.com>

Default rss_hash_key value should be given to all vports. But just the
PF rss_hash_key has the default value here. This patch adds rss_hash_key
Initialization for all vports.

[PATCH net-next 5/5] net: hns3: never send command queue message to IMP when reset

[Peng Li]

IMP will not handle and command queue message any more when it is
in core/global, driver should not send command queue message to
IMP until reinitialize the NIC HW.

This patch checks the status and avoid the message sent to IMP when
reset.
