commit 29a5df0ae41eb7cf6393a0f23cc51c2d3fbe69f1
Diffs: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff;h=29a5df0ae41eb7cf6393a0f23cc51c2d3fbe69f1

tunnel: Mark ECN status on decapsulated tunnel packets.
		
In the kernel tunnel implementation, if a packet was marked as ECN CE on
the outer packet then we would carry this over to the inner packet on
decapsulation.  With the switch to flow based tunneling, this stopped
happening.  This commit reintroduces that behavior by using the set IP
header action.

Bug #15072

tunnel: Generate datapath flows for tunneled packets dropped due to ECN.
		
Move the check for whether tunneled packets should be dropped due to
congestion encountered (CE) when the encapsulated packet is not ECN
capable (non-ECT).  This also adds some additional tests for ECN
handling on tunnel decapsulation.

ofproto-dpif: Store the initial tunnel IP TOS values for later use.
		
When a packet arrives on an IP tunnel, store the TOS value for later
use.  This value will be used in a couple of future commits.

ofproto-dpif: Make initial packet value handling generic.
		
For VLAN splinters, an "initial_tci" value was introduced that is passed
around during flow processing to be used later for action translation.
This commit switches to passing around a struct so that additional
values beyond TCI can be used.  A future commit will use this.

ofproto-dpif: Pass around "facet" in flow_push_stats().
		
The flow_push_stats() function will need other members of the "facet"
structure in a future commit.
