[ovs-dev] [PATCH 2/2] xenserver: Verify md5sums of XenServer host scripts.

[Ben Pfaff]

Commit 34edeccfd8d (xenserver: Remove support for XenServer versions older
than 5.6 FP1.) stopped verifying the md5sums of the XenServer-owned host
scripts that the Open vSwitch RPM replaces.  This commit restores that
behavior, as a small guard against future changes.
