hv_netvsc: Add initialization of tx_table in netvsc_device_add()
tx_table is part of the private data of kernel net_device. It is only zero-ed out when allocating net_device. We may recreate netvsc_device w/o recreating net_device, so the private netdev data, including tx_table, are not zeroed. It may contain channel numbers for the older netvsc_device. This patch adds initialization of tx_table each time we recreate netvsc_device. Signed-off-by: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: David S. Miller <davem@davemloft.net>
