[PATCH 08/12] net/txgbe: fix incorrect device statistics

[Jiawen Wu]

The extend statistic "rx_undersize_errors" is incorrectly read as the
counter of frames received with a length error, which names
"rx_length_error". And "rx_undersize_errors" is the counter of
shorter-than-64B frames received without any errors.

In addition, "tx_broadcast_packets" should use rd64() to get the full
count on the low and high registers.

Fixes: c9bb590d4295 ("net/txgbe: support device statistics")
