Subject: [Qemu-devel] [PATCH v2 2/4] pcie: Rename the pcie_cap_ari_* functions to pcie_cap_arifwd_*
Date: Sun, 24 Aug 2014 15:32:18 +0200	[thread overview]
Message-ID: <1408887140-3320-3-git-send-email-knut.omang@oracle.com> (raw)
In-Reply-To: <1408887140-3320-1-git-send-email-knut.omang@oracle.com>

Rename helper functions to make a clearer distinction between
the PCIe capability/control register feature ARI forwarding and a
device that supports the ARI feature via an ARI extended PCIe capability.
