- Subject: [PATCH 359/454] net: lan78xx: fix rx handling before first packet is
- send
- As long the bh tasklet isn't scheduled once, no packet from the rx path
- will be handled. Since the tx path also schedule the same tasklet
- this situation only persits until the first packet transmission.
- So fix this issue by scheduling the tasklet during ndo_open like in usbnet.
- Link: https://github.com/raspberrypi/linux/issues/2617
- Fixes: 55d7de9de6c3 ("Microchip's LAN7800 family USB 2/3 to 10/100/1000 Ethernet")
