[PATCH 00/10] net: fix problems handling trailing bytes

[Ahmad Fatoum]

This started by pinging a Raspberry Pi 3b running barebox sitting behind
a router employing conntrack. The router discarded the ping responses
due to the wrong ICMP checksum and these issues do not pop up normally
because the ping command itself doesn't bother to verify the checksum.

This unearthed issues in two drivers as well as the barebox network
stack itself.

See the commit messages for details.
