From 7d6da453efce17fae35707fa7e5757e7ade8b3cc Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Sat, 14 May 2016 14:55:49 +0900 Subject: [PATCH] net: w5100: increase TX timeout period This increases TX timeout period from one second to 5 seconds which is the default value if the driver doesn't explicitly set net_device->watchdog_timeo. The one second timeout is too short for W5100 with SPI interface mode which doesn't support burst READ/WRITE processing in the SPI transfer. If the packet is transmitted while RX packets are being received at a very high rate, the TX transmittion work in the workqueue is delayed and the watchdog timer is expired.
