This series includes some misc updates for the HNS3 ethernet driver.
[patch 1] fixes some mixed type operation warning.
[patch 2] renames a macro to make it more readable.
[patch 3 & 4] removes some unnecessary code.
[patch 5] adds check before assert VF reset to prevent some unsuitable
error log.
[patch 6 - 9] some modifications related to printing.
Change log:
V1->V2: fixes a wrong print format in [patch 1] suggested by Jian Shen.
Guojia Liao (2):
net: hns3: fix some mixed type assignment
net: hns3: delete some reduandant code
Huazhong Tan (2):
net: hns3: print out status register when VF receives unknown source
interrupt
net: hns3: synchronize some print relating to reset issue
Yonglong Liu (1):
net: hns3: add a check before PF inform VF to reset
Yufeng Mo (4):
net: hns3: rename macro HCLGE_MAX_NCL_CONFIG_LENGTH
net: hns3: remove an unnecessary resetting check in
hclge_handle_hw_ras_error()
net: hns3: print out command code when dump fails in debugfs
net: hns3: delete unnecessary logs after kzalloc fails

From: Yufeng Mo <[email protected]>
The name of macro HCLGE_MAX_NCL_CONFIG_LENGTH is inaccurate,
this patch renames it to HCLGE_NCL_CONFIG_LENGTH_IN_EACH_CMD.

When received an unknown vector 0 interrupt, there is not a
helpful information for user to realize that now. So this patch
prints out the value of the status register for this case, and
uses dev_info() instead of dev_dbg() in hclge_check_event_cause().

This patch adds a local variable to save the command code in
some dump cases which need to modify the command code, then
the failing command code can be print out for debugging.

In hclge_handle_hw_ras_error(), it is unnecessary to check
HCLGE_STATE_RST_HANDLING flag, because the reset priority
has been ensured by the process itself.

- warning : cast from restricted __le32
- warning : cast from restricted __be32
- warning : cast from restricted __be16
and "mixed operation".

When setting VF's MAC from PF, if the VF driver not loaded, the
firmware will return error to PF.
So PF should check whether VF is alive before sending message to
VF when setting VF's MAC.
