Subject: [PATCHv8 net-next 0/4] sunvnet: add jumbo frames support

From: David L Stevens <[email-masked]>
Date: Mon, 29 Sep 2014 15:53:36 -0400

This patch set updates the sunvnet driver to version 1.6 of the VIO protocol
to support per-port exchange of MTU information and allow non-standard MTU
sizes, including jumbo frames.

Using large MTUs shows a nearly 5X throughput improvement Linux-Solaris
and > 10X throughput improvement Linux-Linux.

Changes from v7:
	-handle skb allocation failures in vnet_skb_shape()
	 per Dave Miller <[email-masked]>
Changes from v6:
	-made kernel transmit path zero-copy to remove memory n^2 scaling issue
	 raised by Raghuram Kothakota <[email-masked]>
Changes from v5:
	- fixed comment per Sowmini Varadhan <[email-masked]>
Changes from v4:
	- changed VNET_MAXPACKET per David Laight <[email-masked]>
	- added cookies to support non-contiguous buffers of max size
Changes from v3:
	- added version functions per Dave Miller <[email-masked]>
	- moved rmtu to vnet_port per Dave Miller <[email-masked]>
	- explicitly set options bits and capability flags to 0 per
		Raghuram Kothakota <[email-masked]>
Changes from v2:
	- make checkpatch clean
Changes from v1:
	- fix brace formatting per Dave Miller <[email-masked]>

David L Stevens (4):
  sunvnet: upgrade to VIO protocol version 1.6
  sunvnet: make transmit path zero-copy in the kernel
  sunvnet: allow admin to set sunvnet MTU
  sunvnet: generate ICMP PTMUD messages for smaller port MTUs
