[PULL 31/51] e1000: Count CRC in Tx statistics


From: Jason Wang
Subject: [PULL 31/51] e1000: Count CRC in Tx statistics
Date: Tue, 7 Mar 2023 15:07:56 +0800

From: Akihiko Odaki <akihiko.odaki@daynix.com>

The Software Developer's Manual 13.7.4.5 "Packets Transmitted (64 Bytes)
Count" says:
> This register counts the number of packets transmitted that are
> exactly 64 bytes (from <Destination Address> through <CRC>,
> inclusively) in length.

It also says similar for the other Tx statistics registers. Add the
number of bytes for CRC to those registers.
