Package: ucarp
Version: 1.5.2-2.2
Severity: wishlist
Tags: patch
This patch adds an environment variable to pass VHID when running the address
up/down commands. This can be useful for scripts to distinguish from
different addresses with its VHID, for example adding the VHID as a virtual
interface name, like 'enp4s0:1'.
