Himanshu Madhani says:

====================
qlcnic: Bug fixes.

This series contains bug fixes for mailbox handling and multi Tx queue support
for all supported adapters.

changes from v1 -> v2
o updated patch to fix usage of netif_tx_{wake,stop} api during link change
  as per David Miller's suggestion.
o Dropped patch to use spinklock per tx queue for more work.
o Added reworked patch for memory allocation failures.
o Added patch to allow capturing of dump, when auto recovery is disabled in firmware.
o Added patches for mailbox interrupt handling and debugging data for mailbox failure.

Please apply to net.
====================
