[Amit Kumar Salecha]

Hi,
   Series of 3 to update qlcnic driver. Apply this to net-next.

[NEXT PATCH 1/3] qlcnic: fix memory leak in qlcnic_blink_led.

[Amit Kumar Salecha]

From: Sucheta Chakraborty <sucheta.chakraborty@qlogic.com>

o Memory allocated in ETHTOOL_ACTIVE mode, is not getting freed. So,
  in ETHTOOL_ID_INACTIVE mode, return after freeing allocated memory.
o Using set bit instead of blink_down field, as it is also required
  in internal Loopback test and etc.

If tx_count cannot be changed, why does qlcnic_get_channels() set
tx_count and max_tx to different values?

Also I don't think you should treat tx_count == 0 as a special case; it
should be rejected as invalid.

Internally both are same values. But I will resubmit the patch to reduce this ambiguity.
