iavf: Add ability to turn off CRC stripping for VF
Previously CRC stripping was always enabled for VF.
Now it is possible to turn off CRC stripping via ethtool:
#ethtool -K <interface> rx-fcs on
To turn off CRC stripping, first VLAN stripping must be disabled:
#ethtool -K <interface> rx-vlan-offload off
if any VLAN interfaces exists, otherwise VLAN stripping will be turned
off by the driver.
In iavf_configure_queues add check if CRC stripping is enabled for
VF, if it's enabled then set crc_disabled to false on every VF's
queue. In iavf_set_features add check if CRC stripping setting was
changed then schedule reset.
