Open-FCoE fixes and features for 2.6.30 merge window

The following series implements a few fixes, some preparation work and the implementation of FIP.

1) Fix of CPU hotplug handling.

2) Removal of fc_transport_fcoe.[ch]. This code was written so a LLD could load a transport for Ethernet devices that support FCoE offloads. This aproach was discarded in favor of directly providing offload capabilities through netdev. FCoE offload patches have been Ack'd by netdev and are in the scsi-misc tree already. In this set we just clean up the previous and unused FCoE transport method.

3) fcoe/* reorgainzation. Since both FIP and fnic are targeting the 2.6.30 merge window we wanted to do some cleanup of the fcoe layer. We've better defined each module so that fcoe.ko will only have the netdev related SW implementation (fnic does not use) and libfcoe.ko which will have common FCoE routines available to all FCoE LLDs.

4) FIP implementation. FIP == FCoE Initialization Protocol. This is a new standard way to discover FCoE capable switches. This code becomes the majority of libfcoe.ko. These patches had previously been sent to linux-scsi. This series resends them as they've been slightly modified to better fit into the reorganization. Functionality is the same as previously posted.

This patchset is built on scsi-misc-2.6 and are intended for 2.6.30.

fcoe: Initialize all possilbe skb_queue(s) when module is loaded

Vasu Dev (8):
fcoe, libfc: fix double fcoe_softc memory alloc
fcoe: cleans up libfcoe.h and adds fcoe.h for fcoe module
fcoe: moves common FCoE library API functions to libfcoe module fcoe, libfc, scsi: adds libfcoe module
fcoe: renames libfcoe.c to fcoe.c as the only fcoe module file
fcoe: removes default sw transport code file fcoe_sw.c
fcoe: removes fc_transport_fcoe.[ch] code files
fcoe: prep work to completely remove fc_transport_fcoe code
