[PATCH net 1/2] bnxt_en: Fix ring arithmetic in bnxt_setup_tc().

[Michael Chan]

The logic is missing the check on whether the tx and rx rings are sharing
completion rings or not.

[PATCH net 2/2] bnxt_en: Fix VF virtual link state.

[Michael Chan]

If the physical link is down and the VF virtual link is set to "enable",
the current code does not always work.  If the link is down but the
cable is attached, the firmware returns LINK_SIGNAL instead of
NO_LINK.  The current code is treating LINK_SIGNAL as link up.
The fix is to treat link as down when the link_status != LINK.

Series applied, thanks Michael.

[PATCH net 0/2] bnxt_en: 2 bug fixes.

[Michael Chan]

The first patch prevents possible driver crash if we get a bad RX index
from the hardware.  The second patch resets the device when the hardware
reports buffer error to recover from the error.

Please queue these for -stable also.  Thanks.

Michael Chan (2):
  bnxt_en: Improve RX consumer index validity check.
  bnxt_en: Reset device on RX buffer errors.

code handling when flashing a file to NVRAM.

Please also queue these for -stable.  Thanks.

Two unrelated fixes.  The first one fixes intermittent false TX timeouts
during ring reconfigurations.  The second one fixes a formatting
discrepancy between the stored and the running FW versions.

Please also queue these for -stable.  Thanks.
