[PATCH net 1/2] iavf: add iavf_schedule_aq_request() helper

[PATCH net 1/2] iavf: add iavf_schedule_aq_request() helper

[Petr Oros]

Add helper for set iavf aq request AVF_FLAG_AQ_* and imediately
schedule watchdog_task. Helper will be used in cases where it is
necessary to run aq requests asap

[PATCH net 2/2] iavf: schedule a request immediately after add/delete vlan

[Petr Oros]

When the iavf driver wants to reconfigure the VLAN filters
(iavf_add_vlan, iavf_del_vlan), it sets a flag in
aq_required:
  adapter->aq_required |= IAVF_FLAG_AQ_ADD_VLAN_FILTER;
or:
  adapter->aq_required |= IAVF_FLAG_AQ_DEL_VLAN_FILTER;

This is later processed by the watchdog_task, but it runs periodically
every 2 seconds, so it can be a long time before it processes the request.

In the worst case, the interface is unable to receive traffic for more
than 2 seconds for no objective reason.

There are other places where the helper can be used without functional 
changes, e.g. iavf_add_fdir_ethtool() , iavf_replace_primary_mac() and 
couple of other places. In all of them, mod_delayed_work() is called 
after setting the AQ flag. For the sake of consistency, can you use the 
helper there too?

These two commits is fixes for issue -> net. But on
iavf_add_fdir_ethtool and iavf_replace_primary_mac is mod_delayed_work
called after spin_unlock_bh ->
looks like no functional chages but i would like be sure and better
will send this to net-next. Are you ok with this?
