2011-06-21ixgbe: setup per CPU PCI pool for FCoE DDPVasu Dev
Currently single PCI pool used across all CPUs and that doesn't scales up as number of CPU increases, so this patch adds per CPU PCI pool to setup udl and that aligns well from FCoE stack as that already has per CPU exch locking. Adds per CPU PCI alloc setup and free in ixgbe_fcoe_ddp_pools_alloc and ixgbe_fcoe_ddp_pools_free, use CPU specific pool during DDP setup. Re-arranged ixgbe_fcoe struct to have fewer holes along with adding pools ptr using pahole.

2011-06-21ixgbe: setup redirection table for multiple packet buffersJohn Fastabend
Setup RSS redirection table to be compatible with multiple packet buffers. Currently, this works on 82599 devices because the RSS redirection index is masked by the number of queues per packet buffer. This sets the cap on the RSS table to maxq.

2011-06-21ixgbe: DCB use existing TX and RX queuesJohn Fastabend
The number of TX and RX queues allocated depends on the device type, the current features set, online CPUs, and various compile flags. To enable DCB with multiple queues and allow it to coexist with all the features currently implemented it has to setup a valid queue count. This is done at init time using the FDIR and RSS max queue counts and allowing each TC to allocate a queue per CPU. DCB will now use available queues up to (8 x TCs) this is somewhat arbitrary cap but allows DCB to use up to 64 queues. Its easy to increase this later if that is needed. This is prep work to enable Flow Director with DCB. After this DCB can easily coexist with existing features and no longer needs its own DCB feature ring.

2011-06-21ixgbe: configure minimal packet buffers to support TCJohn Fastabend
ixgbe devices support different numbers of packet buffers either 8 or 4. Here we only allocate the minimal number of packet buffers required to implement the net_devices number of traffic classes. Fewer traffic classes allows for larger packet buffers in hardware. Also more Tx/Rx queues can be given to each traffic class. This patch is mostly about propagating the number of traffic classes through the init path. Specifically this adds the 4TC cases to the MRQC and MTQC setup routines. Also ixgbe_setup_tc() was sanitized to handle other traffic class value. Finally changing the number of packet buffers in the hardware requires the device to reinit. So this moves the reinit work from DCB into the main ixgbe_setup_tc() routine to consolidate the reset code. Now dcbnl_xxx ops call ixgbe_setup_tc() to configure packet buffers if needed.

2011-06-21ixgbe: consolidate MRQC and MTQC handlingJohn Fastabend
The MRQC and MTQC registers are configured in the main setup path but are also reconfigured in the DCB setup path. The DCB path fixes the DCB configuration by configuring the SECTXMINIFG gap which is required for DCB pause to operate correctly. This patch reduces the duplicate code and does all setup in ixgbe_setup_mtqc() and ixgbe_setup_mrqc(). Additionally, this removes the IXGBE_QDE. This write never set the WRITE bit in the register so the write was not actually doing anything. Also this was to clear the register but, it is never set and defaults to zero. If this is needed for SRIOV it should be added correctly in a follow up patch. But it's never been working so removing it here should be OK.
