igb: Add support for enabling VFs to PF driver.

This patch adds the support to handle requests from the VF to perform
operations such as completing resets, setting/reading mac address, adding
vlans, adding multicast addresses, setting rlpml, and general
communications between the PF and all VFs.

igb: add pf side of VMDq support

Add the pf portion of vmdq support.  This provides enough support so that
VMDq is enabled, and the pf is functional without enabling vfs.

igb: add vfs_allocated_count as placeholder for number of vfs

This is the first step in supporting sr-iov.  The vf_allocated_count value
will be 0 until we actually have vfs present.  In the meantime it
represents an offset value for the start of the queues.

igb: update napi polling to consolidate function and return correct values

igb is currently not returning the correct values for napi.  In addition it
is doing more work than necessary since it will not exit polling until
work_done is equal to zero.

This patch makes the following changes:
1.  Consolidates msi-x and non-msi polling routines.
2.  Corrects return values for polling routines.

   On an idle destination address that is allowed to heartbeat, it is

sctp: Allow to disable SCTP checksums via module parameter

This is a new version of my patch, now using a module parameter instead
of a sysctl, so that the option is harder to find. Please note that,
once the module is loaded, it is still possible to change the value of
the parameter in /sys/module/sctp/parameters/, which is useful if you
want to do performance comparisons without rebooting.

Computation of SCTP checksums significantly affects the performance of
SCTP. For example, using two dual-Opteron 246 connected using a Gbe
network, it was not possible to achieve more than ~730 Mbps, compared to
941 Mbps after disabling SCTP checksums.
Unfortunately, SCTP checksum offloading in NICs is not commonly
available (yet).

By default, checksums are still enabled, of course.
