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.
