Subject: [PATCH v2 net-next 0/8] cdc_ncm: fixes and conversion to sysfs API

After considering the comments received after the ethtool coalesce
support was commited, I have ended up concluding that we should
remove it again, while we can, before it hits a release. The idea
was not well enough thought through, and all comments received
pointed to advantages of using a sysfs based API instead.

This series removes the ethtool coalesce support and replaces it
with sysfs attributes in a driver specific group under the netdev.

The first 3 patches are unrelated fixes:

patch 1: reducing truesize as discussed
patch 2: fixing a potentional buffer overrun when changing tx_max
patch 3: prevent framing errors when changing rx_max


Changes v2:
 - minor editorial changes to patch 8, as suggested by Peter Stuge


Bjørn Mork (8):
  net: cdc_ncm: reduce skb truesize in rx path
  net: cdc_ncm: always reallocate tx_curr_skb when tx_max increases
  net: cdc_ncm: inform usbnet when rx buffers are reduced
  net: cdc_ncm: use sysfs for rx/tx aggregation tuning
  net: cdc_ncm: drop ethtool coalesce support
  net: cdc_ncm: export NCM Transfer Block (NTB) parameters
  net: cdc_ncm: allow tuning min_tx_pkt
  net: cdc_ncm: document the sysfs API
