[PATCH net v01 0/5] net: hinic3: Fix netif_queue_set_napi input parameters and code styles

[Fan Gong]

This patchset provides netif_queue_set_napi bug fix and serveral code styles
fixes to :

Fix netif_queue_set_napi queue_index parameter passing error.
Remove empty lines between error handling.
Remove redundant defensive code.
Use array_size instead of multiplying.
Sq use SQ_CTXT_PREF_CI_HI to improve readability.

Thanks,
Fan gong

[PATCH net v01 1/5] hinic3: Fix netif_queue_set_napi queue_index parameter passing error

[Fan Gong]

Incorrectly transmitted interrupt number instead of queue number
when using netif_queue_set_napi. Besides, move this to appropriate
code location.
Remove redundant netif_stop_subqueue beacuase it is not part of the
hinic3_send_one_skb process.

Sorry for reposting and incorrectly confusing net and net-next.
We will send a new patchset tomorrow and add Fixed tag in patchs for fixes.
