Subject: [PATCH] ixgbe: Fix calculation of queue with VFs and flow director on interface flap

Dear Zhu

Please next time send patch directly to Intel-wired-lan.
All Linux kernel patch submissions and issues reported
against Intel wired Ethernet LAN kernel drivers should 
use this list.

> 
> This patch fixes the calculation of queue when we restore flow director filters
> after resetting adapter. In ixgbe_fdir_filter_restore(), filter's vf may be zero
> which makes the queue outside of the rx_ring array.
> 
> The calculation is changed to the same as ixgbe_add_ethtool_fdir_entry().
>
