====================
net: hns3: some code optimizations & bugfixes & features

This patch-set includes code optimizations, bugfixes and features for
the HNS3 ethernet controller driver.

[patch 1/10] checks reset status before setting channel.

[patch 2/10] adds a NULL pointer checking.

[patch 3/10] removes reset level upgrading when current reset fails.

[patch 4/10] fixes a GFP flags errors when holding spin_lock.

[patch 5/10] modifies firmware version format.

[patch 6/10] adds some print information which is off by default.

[patch 7/10 - 8/10] adds two code optimizations about interrupt handler
and work task.

[patch 9/10] adds support for using order 1 pages with a 4K buffer.

[patch 10/10] modifies messages prints with dev_info() instead of
pr_info().

Change log:
V3->V4: replace netif_info with netif_dbg in [patch 6/10]
V2->V3: fixes comments from Saeed Mahameed and Joe Perches.
V1->V2: fixes comments from Saeed Mahameed and
	removes previous [patch 4/11] and [patch 11/11]
	which needs further discussion, and adds a new
	patch [10/10] suggested by Saeed Mahameed.
