parentnet: w5100: fix MAC filtering for W5500 (diff)
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.
