[PATCH 00/64] libfc, libfcoe and fcoe updates for scsi-misc

[Robert Love <robert.w.love@intel.com>]

These patches are targeting the 2.6.32 merge window.

There are three main focuses in this patch series. First,
there are contributions that modify the stack for VLANs
and prepare for NPIV. For both of those technologies resources
need to be shared between VLANs on a physical port or
VN_Ports on an N_Port. Second, there are improvements to
the discovery and remote port layers. Discovery is now much
more graceful (ADISC) and there is a cleaner division between
fc_rports that are used by the FC transport and libfc's
internal remote port tracking structures. Third, there is
a performance optomization for the exchange manager where
per-CPU exchange ID (XID) pools are created so that each CPU
is not contending for a shared lock when trying to acquire a
new XID.

Other than these primary changes there are other smaller
contributions. A user-tunable DDP limit has been added.
There are various improvements to the debug logging macros
and uses of them. FC headers are exported for user space
tools. The fcoe create/destroy path has been improved.
