net: remove 'fallback' argument from dev->ndo_select_queue() 2019-03-20T18:18:55+00:00 Paolo Abeni pabeni@redhat.com 2019-03-20T10:02:06+00:00 a350eccee5830d9a1f29e393a88dc05a15326d44 After the previous patch, all the callers of ndo_select_queue() provide as a 'fallback' argument netdev_pick_tx. The only exceptions are nested calls to ndo_select_queue(), which pass down the 'fallback' available in the current scope - still netdev_pick_tx. We can drop such argument and replace fallback() invocation with netdev_pick_tx(). This avoids an indirect call per xmit packet in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen) with device drivers implementing such ndo. It also clean the code a bit.

The recent addition of SPDX license identifiers to the files in
drivers/net/ethernet/sun created a licensing conflict.

The cassini driver files contain a proper license notice:

  * This program is free software; you can redistribute it and/or
  * modify it under the terms of the GNU General Public License as
  * published by the Free Software Foundation; either version 2 of the
  * License, or (at your option) any later version.

but the SPDX change added:

   SPDX-License-Identifier: GPL-2.0

So the file got tagged GPL v2 only while in fact it is licensed under GPL
v2 or later.

It's nice that people care about the SPDX tags, but they need to be more
careful about it. Not everything under (the) sun belongs to ...

Fix up the SPDX identifier and remove the boiler plate text as it is
redundant.

net: Use of_node_name_eq for node name comparisons

Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.

For instances using of_node_cmp, this has the side effect of now using
case sensitive comparisons. This should not matter for any FDT based
system which all of these are.
