+Subject: [PATCH] ag71xx: workaround some link state bug
+
+This happens when routing 100mbit/s traffic with masquerading, link
+supposedly drops to 10HD for a few seconds leading to the driver
+reinitialising the NIC and therefore causing a throughput drop. Ignoring
+those link changes allows for constant bandwidth, therefore this seems
+not to be a real problem of the hardware but one of an overreacting
+driver.
