Add the ethtool ops to VF driver to allow querying the RSS indirection table
and RSS Random Key.
 
 - PF driver: Add new VF-PF channel commands.
 - VF driver: Utilize these new commands and add the corresponding
              ethtool callbacks.

New in v4:
   - Forgot to run checkpatch on v3 and there were a few styling things to fix. ;)

New in v3:
   - Added a missing support for x550 devices.
   - Mask the indirection table values according to PSRTYPE[n].RQPL.
   - Minimized the number of added VF-PF commands.
 
New in v2:
   - Added a detailed description to patches 4 and 5.
 
New in v1 (compared to RFC):
   - Use "if-else" statement instead of a "switch-case" for a single option case.
     More specifically: in cases where the newly added API version is the only one
     allowed. We may consider using a "switch-case" back again when the list of
     allowed API versions in these specific places grows up.
