+Subject: [PATCH] ebtables: replace ebtables-save perl script with bash rewrite
+
+Fedora provides a bash replacement for the default ebtables-save perl
+script. Using it allows the ebtables run-time dependency on perl to
+be replaced with a runtime dependency on bash - which is lower
+overhead and more likely to be present on typical embedded systems
+already.
