Subject: [PATCHv5 net-next 0/3] sunvnet: add jumbo frames support

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 > 4X throughput improvement Linux-Solaris
and > 8X throughput improvement Linux-Linux.

Changes from v4:
	- changed VNET_MAXPACKET per David Laight <David.Laight@...LAB.COM>
	- added cookies to support non-contiguous buffers of max size
Changes from v3:
	- added version functions per Dave Miller <>
	- moved rmtu to vnet_port per Dave Miller <>
	- explicitly set options bits and capability flags to 0 per
		Raghuram Kothakota <>
Changes from v2:
	- make checkpatch clean
Changes from v1:
	- fix brace formatting per Dave Miller <>

David L Stevens (3):
  sunvnet: upgrade to VIO protocol version 1.6
  sunvnet: allow admin to set sunvnet MTU
  sunvnet: generate ICMP PTMUD messages for smaller port MTUs
