Commit 1f0f467b "qlcnic: Add hwmon interface to export board

when the hwmon framework is built as a module and the qlcnic
driver itself is built-in:

Ever since v2.3.5 the driver for "Winbond W83977AF (IR)" contains two

CONFIG_ARCH_NETWINDER, so that (valid) Kconfig macro can be used

This introduces another flag in 'quirks' to replace the preprocessor
define (USE_MMIO) used to indicate whether the device needs a
separate enable routine to operate in MMIO mode.

All of the currently known platform Rhine cores operate in MMIO
mode by default, and on PCI it is preferred over PIO for performance
reasons. However, a comment in code suggests that some (?) early
Rhine cores only work in PIO mode, so they should not be switched
to MMIO.

Enabling MMIO on PCI is still triggered by the same Kconfig option
to avoid breaking user configs needlessly, but this can be changed
going forward towards automatic runtime detection in case a list of
PIO-only Rhine revisions can be compiled.

This also fixes a couple of compiler warnings detected by Fengguang
Wu's test bot (!USE_MMIO case):

This adds two new flags to quirks and thus removes the need to carry
revision in rhine_private. As a result, the init logic is simplified
a bit.

We send packets using a copy-free mechanism (this is the Guest to Host transport
via VMBUS). While this is obviously optimal for large packets,
it may not be optimal for small packets. Hyper-V host supports
a second mechanism for sending packets that is "copy based". We implement that
mechanism in this patch.

In this version of the patch I have addressed a comment from David Miller.

With this patch (and all of the other offload and VRSS patches), we are now able
to almost saturate a 10G interface between Linux VMs on Hyper-V
on different hosts - close to  9 Gbps as measured via iperf.

This is a small supplement for commit e7428e95
("virtio-net: put virtio-net header inline with data"). TCP packages have
enough room to put virtio-net header in, but UDP packages do not. By
setting dev->needed_headroom for virtio-net device, UDP packages could have
enough room.

For UDP packages, sk_buff is alloced in fun __ip_append_data. The size is
"alloclen + hh_len + 15", and "hh_len = LL_RESERVED_SPACE(rt-dst.dev);".
The Macro is defined as follows:
#define LL_RESERVED_SPACE(dev) \
     ((((dev)->hard_header_len+(dev)->needed_headroom)\
     &~(HH_DATA_MOD - 1)) + HH_DATA_MOD)
By default, for UDP packages, after skb is allocated, only 16 bytes
reserved. And 2 bytes remained after mac header is set. That is not enough
to put virtio-net header in. If we set dev->needed_headroom to 12 or 10
(according to mergeable_rx_bufs is on or off ), more room can be reserved.
Then there is enough room for UDP packages to put the header in.
