r8169: work around RTL8125 UDP hw bug
[ Upstream commit 8d520b4de3edca4f4fb242b5ddc659b6a9b9e65e ]
It was reported that on RTL8125 network breaks under heavy UDP load,
e.g. torrent traffic ([0], from comment 27). Realtek confirmed a hw bug
and provided me with a test version of the r8125 driver including a
workaround. Tests confirmed that the workaround fixes the issue.
I modified the original version of the workaround to meet mainline
code style.
[0] https://bugzilla.kernel.org/show_bug.cgi?id=209839
v2:
- rebased to net
v3:
- make rtl_skb_is_udp() more robust and use skb_header_pointer()
to access the ip(v6) header
v4:
- remove dependency on ptp_classify.h
- replace magic number with offsetof(struct udphdr, len)
