In order to use offset 0x4014 for reading CAG interrupt status,
the actual CAG register must be mapped to GRC bar0 window #4.
Otherwise, the driver is reading garbage. This patch corrects
this issue.

bnxt_gro_skb() has unused variables when CONFIG_INET is not set.  We
really cannot support hardware GRO if CONFIG_INET is not set, so
compile out bnxt_gro_skb() completely and define BNXT_FLAG_GRO to be 0
if CONFIG_INET is not set.  This will effectively always disable
hardware GRO if CONFIG_INET is not set.

struct bnxt_pf_info needs to be always defined.  Move bnxt_update_vf_mac()
to bnxt_sriov.c and add some missing #ifdef CONFIG_BNXT_SRIOV.

Broadcom ethernet driver for the new family of NetXtreme-C/E
ethernet devices.

v5:
  - Removed empty blank lines at end of files (noted by David Miller).
  - Moved busy poll helper functions to bnxt.h to at least make the
    .c file look less cluttered with #ifdef (noted by Stephen Hemminger).

v4:
  - Broke up 2 long message strings with "\n" (suggested by John Linville)
  - Constify an array of strings (suggested by Stephen Hemminger)
  - Improve bnxt_vf_pciid() (suggested by Stephen Hemminger)
  - Use PCI_VDEVICE() to populate pci_device_id table for more compact
    source.

v3:
  - Fixed 2 more sparse warnings.
  - Removed some unused structures in .h files.

v2:
  - Fixed all kbuild test robot reported warnings.
  - Fixed many of the checkpatch.pl errors and warnings.
  - Fixed the Kconfig description (noted by Dmitry Kravkov).
