> 
> This patch extends the reporting of the RSS key and hash table by adding support
> for X550 VFs. The difference is that X550 VFs have their own registers for RSS
> key and indirection table, so there is no need to query the PF.
> 
> The RSS key and indirection table are stored in the adapter structure during the
> configuration of VFRSSRK and VFRETA which in turn can be used in ethtool for
> reporting.
> 
> The logic for writing VFRETA is also changed to make sure that the indirection
> table is reported correctly.
> 
> In addition this patch adds defines for the VFRETA entries and number of
> VFRSSRK registers as well as some whitespace cleanups.
