[PATCH net 0/3] qlcnic: Bug fixes

[Shahed Shaikh]

From: Shahed Shaikh <shahed.shaikh@qlogic.com>

This patch series contains bug fixes for -
* Loopback test failure while traffic is running.
* Tx timeout and subsequent firmware reset by removing check for
  '(adapter->netdev->features & (NETIF_F_TSO | NETIF_F_TSO6)' from tx fast
  path, as per Eric's suggestion.
* Typo in logs.

Please apply to net.

Thanks,
Shahed

[PATCH net 1/3] qlcnic: Stop traffic before performing loopback test

[Shahed Shaikh]

From: Jitendra Kalsaria <jitendra.kalsaria@qlogic.com>

Before conducting loopback test by sending packets, driver should stop transmit
queue and turn off carrier.

[PATCH net 2/3] qlcnic: fix TSO race condition

[Shahed Shaikh]

From: Sritej Velaga <sritej.velaga@qlogic.com>

When driver receives a packet with gso size > 0 and when TSO is disabled,
it should be transmitted as a TSO packet to prevent Tx timeout and subsequent
firmware reset.
