Subject: [PATCH v4 0/5] net: Unified offload configuration

Here's a v4 of the ethtool unification patch series.

What's in it?
 1:
	the patch - implement unified ethtool setting ops
 2..3:
	implement interoperation between old and new ethtool ops
 4:
	include RX checksum in features and plug it into new framework
 5:
	convert loopback device to new framework

What is it good for?
 - unifies driver behaviour wrt hardware offloads
 - removes a lot of boilerplate code from drivers
 - allows better fine-grained control over used offloads

I'm testing this on ARM Gemini arch now. Patch to ethtool userspace tool
will follow this series. I'm not fond of the GFEATURES output I implemented -
please throw some suggestions on it if you can.

Driver conversions stay the same as in v2 - as for v3, I'll keep them
from resending until after the core code gets accepted.

Patches 2,4,5 are unchanged from v3.

Best Regards,
Michał Mirosław


v1: http://marc.info/?l=linux-netdev&m=129245188832643&w=3

Changes from v3:
 - fixed kernel-doc and other comments
 - added HIGHDMA to never-changeable features
 - changed GFEATURES .size interpretation
 - changed feature strings
 - change __ethtool_set_flags() to reject invalid changes

Changes from v2:
 - rebase to net-next after merging v2 leading patches
 - fix missing comma in feature name table
 - force NETIF_F_SOFT_FEATURES in hw_features for simpler code
   (fixes a bug that disallowed changing GSO and GRO state)

Changes from v1:
 - split structures for GFEATURES/SFEATURES
 - naming of feature bits using GSTRINGS ETH_SS_FEATURES
 - strict checking of bits used in SFEATURES call
 - more comments and kernel-doc
 - rebased to net-next after 2.6.37
