The underlying Ethernet device may request necessary tailroom to be
allocated by setting needed_tailroom. This driver should also set
needed_tailroom to request the tailroom needed by the underlying
Ethernet device to be allocated.

Change from v1:
None
I'm re-sending this patch unchanged because the previous reviewer has
stopped responding for 11 days and he didn't indicate what change I
should do to this patch.
It's hard to find reviewers for this code. I tried to send emails, but
people don't respond. If you can review it, I'd really appreciate it.
I'm not in a hurry so please take your time. Thanks!
