Subject[PATCH] ucc_geth: invalid rx checksum error values

The value in QE UCC ethernet interfaces shows random values:

# ethtool -S eth0
NIC statistics:
rx-ip-checksum-errors: 3933892214

The problem is located in a mismatch between the rx_fw_stat_gstrings fields
- used in ucc_geth_ethtool - and the ucc_geth_rx_firmware_statistics_pram
fields - used in ucc_geth.
Although the QE UCC Ethernet Controller includes the Rx checksum error
counter in the 'Rx firmware counters', the related field is missing from the
ucc_geth driver.
After adding the RxChecksumError field in
ucc_geth_rx_firmware_statistics_pram structure the counter works fine.
