Vasundhara Volam a60faa60da bnxt_en: Fix memory fault in bnxt_ethtool_init()
In some firmware images, the length of BNX_DIR_TYPE_PKG_LOG nvram type
could be greater than the fixed buffer length of 4096 bytes allocated by
the driver.  This was causing HWRM_NVM_READ to copy more data to the buffer
than the allocated size, causing general protection fault.

Fix the issue by allocating the exact buffer length returned by
HWRM_NVM_FIND_DIR_ENTRY, instead of 4096.  Move the kzalloc() call
into the bnxt_get_pkgver() function.

Rob Swindell a4c363471f bnxt_en: Add support for updating flash more securely
To support Secure Firmware Update, we must be able to allocate
a staging area in the Flash.  This patch adds support for the
"update" type to tell firmware to do that.

Rob Swindell 3ebf6f0a09 bnxt_en: Add installed-package firmware version reporting via Ethtool GDRVINFO
For everything to fit, we remove the PHY microcode version and replace it
with the firmware package version in the fw_version string.

Michael Chan c0c050c58d bnxt_en: New Broadcom ethernet driver.
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).
