Merge branch 'hns3-next'
Huazhong Tan says:
====================
net: hns3: misc updates for -net-next
This series includes some misc updates for the HNS3 ethernet driver.
[patch 1] adds a limitation for the error log in the
hns3_clean_tx_ring().
[patch 2] adds a check for pfmemalloc flag before reusing pages
since these pages may be used some special case.
[patch 3] assigns a default reset type 'HNAE3_NONE_RESET' to
VF's reset_type after initializing or reset.
[patch 4] unifies macro HCLGE_DFX_REG_TYPE_CNT's definition into
header file.
[patch 5] refines the parameter 'size' of snprintf() in the
hns3_init_module().
[patch 6] rewrites a debug message in hclge_put_vector().
[patch 7~9] adds some cleanups related to coding style.
