====================
sunvnet: bug fixes

This patch series has a coding-style fix and a bug fix.

The coding style fix (patch 1) is the extra indentation flagged by
Ben Hutchings:
  http://marc.info/?l=linux-netdev&m=141529243409594&w=2



The bugfix (patch 2) is the following:
when vnet_event_napi() is  called as part of napi_resume
(i.e., continuation of a previous NAPI read that was truncated
due to budget constraints), and then finds no more packets to read,
the code was trying to avoid an additional trip through ldc_rx
as an optimization. However, when this corner case happens, we would
need to reset a number of dring state bits such as rcv_nxt carefully,
which quickly becomes complex and hacky.  The cleaner solution
is to just roll back to vnet_poll, re-enable interrupts and set up
dring state as was done in the pre-NAPI version of the driver.
