igc: Add ndo_tx_timeout support
[ Upstream commit 9b275176270efd18f2f4e328b32be1bad34c4c0d ]
On some platforms, 100/1000/2500 speeds seem to have sometimes problems
reporting false positive tx unit hang during stressful UDP traffic. Likely
other Intel drivers introduce responses to a tx hang. Update the 'tx hang'
comparator with the comparison of the head and tail of ring pointers and
restore the tx_timeout_factor to the previous value (one).
This can be test by using netperf or iperf3 applications.
Example:
iperf3 -s -p 5001
iperf3 -c 192.168.0.2 --udp -p 5001 --time 600 -b 0
netserver -p 16604
netperf -H 192.168.0.2 -l 600 -p 16604 -t UDP_STREAM -- -m 64000
