====================
net/mlx4: Mellanox driver update 08-12-2013

This patchset contains:
1. Support in ndo_get_phys_port_id added by Hadar.
2. Change the driver to use by default CQE/EQE size of 64 bytes done by Eyal.
   This doubles the packet-rate  of the NIC.
3. Configure the XPS queue mapping on driver load - added by Ido.
4. Fixes for some small bugs done by Jenny and Matan

Patchset was applied and tested against commit: "2372175 lib: hash: follow-up
fixups for arch hash"

Changes from V1:
- Removed Patch 10 "net/mlx4_en: Fix Supported/Advertised link mode reported by
  ethtool". This patch is needed to be rewritten from scratch and I wouldn't
  like it to block the rest of the patches in this set.
  Also, fix to Kconfig suggested by Ben will be sent in next patchset.

Changes from V0:
- Found some issues in "Reuse memory in RX flow" patch from V0.
  Removing this patch from the patchset till analyzed and fixed.
- Fix some coding style issues in patch 6 "Configure the XPS queue mapping on
  driver load"
- Changed patch 9 "Add NAPI support for transmit side" to use NAPI_POLL_WEIGHT
  instead of MLX4_EN_TX_BUDGET
