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 v1:
- fix brace formatting per Dave Miller [off-list ref]
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
