Ok, I see the problem. I think the solution looks good as Daniele said in a
separate thread. As
mentioned, the flush logic needs a bit of a refactoring but this solution looks
ok at this point.

Hi Ben,
XenServer 6.6 (still to be released) will ship with Python 2.7 as the
system python. Nightlies are currently available at xenserver.org.
Versions of XenServer below 6.6 will need Python 2.7 installed probably via
RPMs, like you suggested.

When using multiple PMDs and numerous ports, a performance gain
may be achieved in some use cases by pinning a PMD/port to a

This patch provides a summary of the switch's port/core affinities

This patch sacrifices a few bits of hash quality from the 128-bit unique
flow identifiers to make the UFIDs RFC4122-conformant as per the version 4
(random) UUID spec. Given that the 128-bit space is already quite large,
this should not affect the spread of UFIDs in any meaningful way for
hashing.

We set this field flag for the cases when an out_port should be
parsed, but failed to make use of it.
Two test cases needed to be updated due to use of out_port in flow
add, while out_port is legal for flow deletes only.

GCC 4.7.2 -O3 flagged potential use before initialization for the 'id'
and 'id_mask' being scanned in scan_vxlan_gbp(). For the 'id' this
was a real possiblity, but for the 'id_mask' it seems to be a false
positive in gcc analysis. Simplify scan_vxlan_gbp() to fix this.

This patch allows classifier rules to become visible and invisible in
specific versions. A 'version' is defined as a positive monotonically
increasing integer, which never wraps around.
The new 'visibility' attribute replaces the prior 'to_be_removed' and
'visible' attributes.

Handling evictions was broken in the previous patches. Eviction took
