Remove HV_DRV_VERSION, it has no meaning for upstream drivers.
Initially it was supposed to show the "Linux Integration Services"
version, now it is not in sync anymore with the out-of-tree drivers
available from the MSFT website.The only place where a version string is still required is the KVP
command "IntegrationServicesVersion" which is handled by
tools/hv/hv_kvp_daemon.c. To satisfy such KVP request from the host pass
the current string to the daemon during KVP userland registration.Signed-off-by: Olaf Hering

Fixed: warning: cast from pointer to integer of different size
The Hyper-V hosts always use 64 bit request id. The guests can have 32 or 64
bit pointers which equal to the ulong type size. So we cast it to ulong type.
And, assigning 32bit integer to 64 bit variable works fine.The VMBus returns the same id in the completion packet. But the value has no
effect on the host side.Reported-by: kbuild test robot

interface changes by Patrick McHardy in net-next.An IGB conflict existed because in 'net' the build_skb() support was
reverted, and in 'net-next' there was a comment style fix within that
code.Several batman-adv conflicts were resolved by making sure that all
calls to batadv_is_my_mac() are changed to have a new bat_priv first

In some cases, the VM_PKT_COMP message can arrive later than RNDIS completion
message, which will free the packet memory. This may cause panic due to access
to freed memory in netvsc_send_completion().This patch fixes this problem by removing rndis_filter_send_request_completion()
from the code path. The function was a no-op.Reported-by: Long Li

The warning about local_bh_enable inside IRQ happens when disconnecting a
virtual NIC.The reason for the warning is -- netif_tx_disable() is called when the NIC
is disconnected. And it's called within irq context. netif_tx_disable() calls
local_bh_enable() which displays warning if in irq.The fix is to remove the unnecessary netif_tx_disable & wake_queue() in the
netvsc_linkstatus_callback().Reported-by: Richard Genoud

Although the network interface is down, the RX packets number which
could be observed by ifconfig may keep on increasing.This is because the WORK scheduled in netvsc_set_multicast_list()
may be executed after netvsc_close(). That means the rndis filter
may be re-enabled by do_set_multicast() even if it was closed by
netvsc_close().By canceling possible WORK before close the rndis filter, the issue
could be never happened.Signed-off-by: Wenqi Ma

In the existing code, we only stop queue when the ringbuffer is full,
so the current packet has to be dropped or retried from upper layer.This patch stops the tx queue when available ringbuffer is below
the low watermark. So the ringbuffer still has small amount of space
available for the current packet. This will reduce the overhead of
retries on sending.Signed-off-by: Haiyang Zhang

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

A driver start_xmit() method cannot free skb and return NETDEV_TX_BUSY,
since caller is going to reuse freed skb.This is mostly a revert of commit bf769375c (staging: hv: fix the return
status of netvsc_start_xmit())In fact netif_tx_stop_queue() / netif_stop_queue() is needed before
returning NETDEV_TX_BUSY or you can trigger a ksoftirqd fatal loop.In case of memory allocation error, only safe way is to drop the packet
and return NETDEV_TX_OKSigned-off-by: Eric Dumazet
