Subject: [PATCH net v2 1/8] qlcnic: Fix usage of netif_tx_{wake,stop} api during link change.

From: Himanshu Madhani <himanshu.madhani@...gic.com>

o Driver was using netif_tx_{stop,wake}_all_queues() api
  during link change event. Remove these api calls to
  manage queue start/stop event, as core networking stack
  will manage this based on netif_carrier_{on,off} call.
  These API's were modified as part of commit id
  012ec81223aa45d2b80aeafb77392fd1a19c7b10 ("qlcnic: Multi Tx
  queue support for 82xx Series adapter.")
