Haiyang Zhang da24e906cb net/hyperv: Fix the code handling tx busy ... Instead of dropping the packet, we keep the skb buffer, and return NETDEV_TX_BUSY to let upper layer retry send. This will not cause endless loop, because the host is taking data away from ring buffer, and we have called the stop_queue before returning NETDEV_TX_BUSY. The stop_queue was called in the function netvsc_send() in file netvsc.c, then it returns to rndis_filter_send(), which returns to netvsc_start_xmit() in file netvsc_drv.c. So the NETDEV_TX_BUSY is indeed returned AFTER queue is stopped. Signed-off-by: Haiyang Zhang <haiyangz@microsoft.com> Reviewed-by: K. Y.
