Subject: OXM inspired match field names.
X-Git-Tag: sliver-openvswitch-2.0.90-1~6^2~38
X-Git-Url: http://git.onelab.eu/?p=sliver-openvswitch.git;a=commitdiff_plain;h=44a7e26dcc2a68c0293b38c03048f938f318f0fd

OXM inspired match field names.

Adds OXM inspired aliases for match fields that don't have them
already ("ip_proto", "ip_ecn", "ip_dscp", and "tunnel_id").

"ip_dscp" replaces the earlier undocumented "nw_tos_shifted",
and takes the DSCP value (0-63), which is then shifted
appropriately when applied to an IP packet.
The number of bits for this field is fixed from 8 to 6.
