Subject: [PATCH net 0/3] bnxt_en: Fix RTNL lock usage in bnxt_sp_task().

There are 2 function calls from bnxt_sp_task() that have buggy RTNL
usage.  These 2 functions take RTNL lock under some conditions, but
some callers (such as open, ethtool) have already taken RTNL.  These
3 patches fix the issue by making it clear that callers must take
RTNL.  If the caller is bnxt_sp_task() which does not automatically
take RTNL, we add a common scheme for bnxt_sp_task() to call these
functions properly under RTNL.

Michael Chan (3):
  bnxt_en: Fix bnxt_reset() in the slow path task.
  bnxt_en: Fix RTNL lock usage on bnxt_update_link().
  bnxt_en: Fix RTNL lock usage on bnxt_get_port_module_status().
