The patch set simplifies the existing hash level switching code for
UDP. It also adds the support for changing TCP hash level. So users
can switch between L3 an L4 hash levels for TCP and UDP.

The patch supports the options to switch TCP hash level between
L3 and L4 by ethtool command. TCP over IPv4 and v6 can be set
differently. The default hash level is L4. We currently only
allow switching TX hash level from within the guests.
For example, for TCP over IPv4 on
From: Haiyang Zhang
For older hosts without multi-channel (vRSS) support, and some error
cases, we still need to set the real number of queues to one.
This patch adds this missing setting.

This patch set cleans up some unused variables, unnecessary checks.
Also fixed some limit checking of channel number.

hv_netvsc: Simplify num_chn checking in
From: Haiyang Zhang
The minus one and assignment to a local variable is not necessary.
This patch simplifies it.

Because of the following code, net->num_tx_queues equals to
VRSS_CHANNEL_MAX, and max_chn is less than or equals to VRSS_CHANNEL_MAX.

alloc_etherdev_mq(sizeof(struct net_device_context),
VRSS_CHANNEL_MAX);

From: Haiyang Zhang
The limit of setting receive indirection table value should be
the current number of channels, not the VRSS_CHANNEL_MAX.

We now remove rndis filter before unregister_netdev(), which calls
device close. It involves closing rndis filter already removed.
This patch fixes this error.
