[PATCH net-next 00/10] more s390/net updates

[Julian Wiedmann]

Hi Dave,

here's a second batch of s390/net patches for net-next.
A mixed bunch of qeth cleanups, and a few patches to add support for
ETHTOOL_GLINKSETTINGS.

Thanks,
Julian

Julian Wiedmann (10):
  s390/qeth: move common ioctl handling to core
  s390/qeth: move NAPI poll routine to core
  s390/qeth: move gdev shutdown handler to core
  s390/qeth: remove unused parameter
  s390/qeth: use correct return type for hard_start_xmit()
  s390/qeth: use and remove some defines
  s390/qeth: clean up qeth_set_ecmd_adv_sup()
  s390/qeth: convert to ETHTOOL_GLINKSETTINGS API
  s390/qeth: use LINK_MODE_* to report the link characteristics
  s390/qeth: remove unimplemented gdev routines

[PATCH net-next 02/10] s390/qeth: move NAPI poll routine to core

[Julian Wiedmann]

Identical code, we just need to call a layer-specific hook
to process any received buffer.

qeth_buffer_reclaim_work() is shuffled around to avoid a
forward declaration for qeth_queue_input_buffer().

[PATCH net-next 02/10] s390/qeth: move NAPI poll routine to core

[Julian Wiedmann]

Identical code, we just need to call a layer-specific hook
to process any received buffer.

qeth_buffer_reclaim_work() is shuffled around to avoid a
forward declaration for qeth_queue_input_buffer().
