Pull request: Fixes for new ethtool RSS commands

This addresses several problems I previously identified with the new
ETHTOOL_{G,S}RSSH commands:

1. Missing validation of reserved parameters
2. Vague documentation
3. Use of unnamed magic number
4. No consolidation with existing driver operations

I don't currently have access to suitable network hardware, but have
tested these changes with a dummy driver that can support various
combinations of operations and sizes, together with (a) Debian's ethtool
3.13 (b) ethtool 3.14 with the submitted patch to use ETHTOOL_{G,S}RSSH
and minor adjustment for fixes 1 and 3.

v2: Update RSS operations in vmxnet3 too
