One empty line is sufficient, we don't need two of them here.

We no longer use extern in header file function declarations.

Again, one empty line is enough.

Again, please remove this extern in function declarations.

For the second time, this is not properly indented. Multi-line
conditionals should be formatted like this:
if (CONDITION1 OPERATOR
CONDITION2 OPERATOR
...)
etc. For example, this specifically should be:
if (netif_tx_queue_stopped(netdev_get_tx_queue(ndev, q_idx)) &&
!net_device->start_remove &&
(hv_ringbuf_avail_percent(&channel->outbound) >
RING_AVAIL_PERCENT_HIWATER || queue_sends < 1))
Generally speaking, if you are only using TAB characters to indent,
you are probably doing it wrong.
You should use the appropriate number of TAB _and_ SPACE characters
necessary to start the line at exactly the first column after the
openning parenthesis of the appropriate construct.

num_online_cpus() can change, will your driver accomodate this?

One empty line is sufficient.

Likewise.

When function arguments span multiple lines the function call
shall be indented as:
func(A, B, C,
D, E, F);
That is, the second and subsequent lines are indented, using
the appropriate number of TAB _and_ SPACE characters, necessary
to reach exactly the first column after the openning parenthesis.
There are several other cases of this, please audit your entire
submission for this problem.
If proper indentation causes lines to significantly exceed 80
columns, consider helper functions or local variables to
allieve the problem.

Same problem.
