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.
