Jesse Brandeburg dddd406d9d ice: Implement control of FCS/CRC stripping 
The driver can allow the user to configure whether the CRC aka the FCS
(Frame Check Sequence) is DMA'd to the host as part of the receive
buffer.  The driver usually wants this feature disabled so that the
hardware checks the FCS and strips it in order to save PCI bandwidth.

Control the reception of FCS to the host using the command:
ethtool -K eth0 rx-fcs <on|off>

The default shown in ethtool -k eth0 | grep fcs; should be "off", as the
hardware will drop any frame with a bad checksum, and DMA of the
checksum is useless overhead especially for small packets.

Testing Hints:
test the FCS/CRC arrives with received packets using
tcpdump -nnpi eth0 -xxxx
and it should show crc data as the last 4 bytes of the packet. Can also
use wireshark to turn on CRC checking and check the data is correct.
