Cleanup bnxt_probe_phy() to cleanly separate 2 code blocks for autoneg
on and off. Autoneg flow control is possible only if autoneg is enabled.
In bnxt_get_settings(), Pause and Asym_Pause are always supported.
Only the advertisement bits change depending on the ethtool -A setting
in auto mode.

1. Determine autoneg on|off setting from link_info->autoneg. Using the
firmware returned setting can be misleading if autoneg is changed and
there hasn't been a phy update from the firmware.
2. If autoneg is disabled, link_info->autoneg should be set to 0 to
indicate both speed and flow control autoneg are disabled.
3. To enable autoneg flow control, speed autoneg must be enabled.

Use HWRM_FW_RESET command to request a self-reset of the embedded
processor(s) after successfully applying a firmware update. For boot
processor, the self-reset is currently deferred until the next PCIe reset.

The driver can support either all combined or all rx/tx rings. The
default is combined, but the user can now select rx/tx rings.

Add logic to calculate how many shared or non shared rings can be
supported. Default is to use shared rings.

The hardware resources required to enable NTUPLE varies depending on
how many rx channels are configured. We need to make sure we have the
resources before we enable NTUPLE. Add bnxt_rfs_capable() to do the
checking.
In addition, we need to do the same checking in ndo_fix_features(). As
the rx channels are changed using ethtool -L, we call
netdev_update_features() to make the necessary adjustment for NTUPLE.
Calling netdev_update_features() in netif_running() state but before
calling bnxt_open_nic() would be a problem. To make this work,
bnxt_set_features() has to be modified to test for BNXT_STATE_OPEN for
the true hardware state instead of checking netif_running().

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).
